Boat: Fiberglas shattering 44' steel trawler | supplies such detailed instructions for this . I'm also impressed that your yard dues such a careful analysis of the task. The only thing that doesn't impress me is the original design of the strut - as long as they were casting it, a horizontal flnge with bolts would seem in order. Dezincification should be evident on close examination fo the lower part of the strut, if it exists. I can't help you on a source, but I am doubting that you need one. With such careful instructions, are you considering doing this job yourself? It's long and complicated, but none of the individual tasks is challenging. You would determine whether the plywood triangles can be salvaged when you get down to them, and they are easy to replace if needed. |

Boat: Owner built 60 Aluminum Expedition Yacht. | has gone into great detail, is this a common problem with your model boat. Are you asking our repair opinions because you wish to or are you asking about the yard estimate. The next question is simple. Is the strut loose in the or is the flexing. Does the strut move side to side , fore and aft or only up and down. Does the prop shaft turn more easily of you push up or down on the strut. Did you have a lot of leaking past the stuffing box or any other symptoms which got you to look at the strut. Well the Green Frog is correct. A tee shaped strut is a much stronger design. It spreads the load. So...lets take a look at repair options...DIY. You will make things a lot worse if everything is not kept in alignment...so let this be your priority. Remember the weight of your or any mis alignment of your will defeat the repair so off goes the prop and disconnect the . How far off is the engine with the strut loose. Can you prop up the strut so you are pretty closely aligned to the engine as is? What we are trying to figure out is a fix without tearing the box surrounding the strut inside the hull, apart completely. IF...and its a big IF, the strut is just loose in that box support thing inside the hull...and IF the shaft is centered in the tube, then it MIGHT be possible to fix it by injection. A few small holes drilled into the box till you hit the strut will tell you if the plywood is wet. If it is...then a simple repair no longer is possible. You could add angled supports on the hull exterior or bolted both to the strut and hull but it would be a lot of . We dont recommend rebuilding the box support system recommended by the . You can cut the box flat to the of the hull...have a tee shaped strut welded or cast . Wed lay up a nice wide area of reinforcement to the hull and bolt the new strut to reinforcements inside the hull. Please let us know if you intend to . My Green web footed friend exists on a diet of flying insects, lives on an unstable wet pad of dubious strength, and makes the beginning of a nice Cajun dinner...BUT ...he is very knowledgeable, kind and helpful. Thus we leave you in his capable hands as the manatee crew wishes you...happy trails. Mark |

Boat: Beneteau First 42 | damage or just from normal wear. I may take on the task myself. Time is the biggest factor right now. I had the boat pulled just to put on a coat of and upgrade my and speed through hole sensors so I hadnt planned on tackling such a big job right now. My first step will be to sand and clean the strut to bright metal to determine the extent of the dezincification to assess if it is still sound. My thought is, if I am going to pay the yard to remove the strut for I may as well have a new one, possibly cast out of bronze, installed. Im meeting with the yard manager in a few days to discuss the specifics on how much of the housing they intend to prior to re-bonding the strut into place. |

Boat: Beneteau First 42 | Mark. The strut mostly has vertical play. I will assess side to side movement tomorrow when I can get down to the yard. It appears to be still in horizontal alignment and I havent seen signs of hull flex or damage. The prop turns freely and the wasnt leaking. The loose strut was discovered while pushing up on the prop to check the cutlass bearing. The shaft is centered in the log horizontally but is closer to the bottom of the log. I attributed this to hull deformation due to its resting on the while . I have experience aligning a shaft flange to a . I did that job on another boat after replacing the cutlass bearing. Thank you for your suggestion on drilling into the ply squares to test their integrity. From the document it seems like the ply is initially installed to set alignment then also supply lateral support to the final build. Maybe sistering the squares with new glassed in ply on the outside of the existing housing would supply enough support? I feel the simplest patch fix would be to cut the top off of the glass strut housing, clean the inside as best as possible, realign the strut with the shaft in place and fill the housing with . The most complicated repair involves removing and rebuilding the entire strut housing as per the Beneteau publication. Im assuming the yard is proposing something in the middle of those two extremes. Their description in the estimate was somewhat vague. As to whether I do this job myself or hire the yard I havent decided yet. Either way I want to understand and weigh all options. |

Boat: Beneteau First 42 | and I am open to alternatives. If I am understanding, you are both suggesting a flanged strut through bolted to the bottom of the hull to a bedded backing plate on the inside? That does sound like a stronger solution than the original design. If I were to get a bronze replacement of the original strut cast I would be able to do the machining of the strut myself. |

My three choices for the repair are; 1) buy a new "close fitting" strut from Bock Algonguin, $ 600.+. 2) cut existing strut out and weld/braze on a flange (bronze) 3) fab a new strut out of stainless. I have access to a full on machine shop and can do most of the work myself, zero boat $. All three options involve cutting the existing strut out ...

14. Catalina 30 San Diego. Jun 28, 2022. #1. Just finished a pre-purchase survey for a 1986 Catalina 30 and the survey found the strut to be loose. He applied push and pull pressure on it and there was substantial movement and a popping noice. The fiberglass hull around the strut was cracked and soft meaning there was some water damage.
Sep 20, 2014. #2. Kito: The strut on my 1980 Cherubini Hunter 36 needed replacement this past summer when it cracked while the yard tried to press out the cutlass bearing. I was 75% expecting this outcome because before the project, I had previously noted that the bronze strut had "gone pink" in several spots.
New here, did a little searching but didn't find anything on how to repair a leaking strut. I'm helping a friend on his 64' Harkers Islans Kingfisher. The STBD strut leaks, so we pulled her out of the water and I've gone to work. Of the 6 bolts that hold the strut on to the hull one is spun out and two look like they are leaking water ...
Beneteau First 42 Prop strut repair. The strut has vertical movement/play of about 3/8".

The strut bolts are drilled out to remove the filler material and the bolts are put back in place with 5200. Aligning a strut is usually a once in a boat-life project unless a catastrophic grounding occurs. A properly aligned strut will free-up an engine to provide a smooth ride for comfort and higher speed, lower fuel consumption for performance.
A bent shaft can be repaired. We use a cold, hydraulic press process that does not alter the metallurgy of the shaft. It takes a lot of practice and time to straighten a shaft. Some shafts have metal memory and need to be checked hours or a day later. If the shaft is bent badly enough (over 1/2″) we will run a red dye crack test when the ...

Boat: 2005 23 LSV. 1. Author. Posted July 3, 2008. Here's the tally: at Malibu dealer, new rudder is $549 and strut is $216. here in the fine city of Houston, "Bauman's Props", a well-known machine shop that builds and reconditions props, quoted $60 each to straighten strut and rudder, provided they are not too bent.
I removed the strut on my 1980 H27 when I replaced the cutlass bearing. Get new bearings at West Marine or other chandlery. On my H27, you can unscrew the plywood panel at the quarter berth to get to the strut nuts. I found that to align the strut after removal is the hard part. I had to shim under the strut with washers to get it to align right.
62,321. Oct 2, 2008. #2. Re: inboard strut alignment. Struts can be bent, and straightened. I've done a couple this year that had bent shafts and struts. Check both or you NEVER will get the alignment right. Most prop shops can check and repair struts, shafts are replaced if bent, along with the coupler on the tranny end of the shaft.

Mar 22, 2011. #4. As I'm sure you know, you must align the engine and shaft with the boat in the water. The strut and cutless bearing should be as close in alignment as you can get with the boat on the hard, which will give the proper engine alignment when the boat is back in the water. So your short answer is align strut and shaft, then align ...

Apr 22, 2011. 887. Hunter 27 Pecan Grove, Oriental, NC. Apr 26, 2021. #7. My 84 H27 prop strut is a Buck Algonquin. It is mounted with four 1/4" flat head bolts. There is a ss backing plate for each set of 2 bolts. I don't think that Hunter would have mounted your strut with only 2 bolts.
