    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider I had an open weekend, so I decided to get back at the boat. Earlier in the week, I spent a few hours and cut some foam-board templates of the deck sections and I was able to get the deck boards cut out of the Aurauco plywood. It took a...

    Recommendations for replacement bolster seat

    Hi, I'm doing a bunch of work on my 19' Larson 186 SEI bowrider. I want to replace the captain's chair -- it's currently a pedestal mounted bucket seat with no bolster (has slider base with 5x12 mounting holes). I find myself standing quite often anyway, so I'd like to find a bolster to get an...

    removing motor and outdrive

    Re: removing motor and outdrive Those are some weird fasteners, aren't they? I tried all sorts of things... even bought a set of Torx sockets that didn't work. Eventually, I found some 12-point sockets at AutoZone that worked. I don't remember which size I used, but here is a picture of one of...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider I took advantage of an unusually warm January day here in Illinois to see if I could glass in the engineered stringers I had to remove to drop in the new transom. I kept the pieces I cut out -- they have a foam core and a shell of gelcoated...

    How to match gel coat color?

    Re: How to match gel coat color? I've got a thread detailing the whole project at http://forums.iboats.com/boat-restoration-building-hull-repair/transom-problems-larson-186-sei-i-o-bowrider-570875.html. I haven't take any picture since I completed grinding, but here's a pic that gives you a...

    Extra part in impeller kit?

    I'm replacing the impeller in my Alpha One Gen 2 outdrive, following the instructions put together by Don S. that I found up in the stickies. I've also watched a couple of Youtube videos of the procedure. I have the drive split and I've removed the old impeller parts. The old impeller looked a...

    How to match gel coat color?

    As part of my '97 Larson restoration, I need to gelcoat some parts of the bilge and vicinity that had to be cut away and/or ground down. Is there any way, other than trial and error, to get a reasonably close match on the gel coat color? It's an off-white; a pure white gel coat won't look very...

    New gimbal housing gasket?

    I am restoring an I/O and I'm trying to amass any new gaskets or seals I'll need when it's reassembly time. Is the gimbal housing gasket a "must replace" piece when reassembling the engine/outdrive? The curent gasket looks/feels OK, but I've done some searching here and on the web, and I can't...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider I took advantage of some warm weather this weekend and finished the glassing of the transom core. Per Woodonglass's transom how-to instructions, I added fillets around the edges of the transom and tabbed it in with CSM. Since the tabbing on...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider Well, the transom core is in. It went pretty well, I think, except that I ran out of Cabosil and couldn't finish the fillets. Here are a few pics of my progress. I was worried about the clamps causing uneven thickness around the keyhole, so...

    Larsons and trim tabs.

    Re: Larsons and trim tabs. I posed the installation question (re: installing SmartTabs on a Larson's contoured transom) to Nauticus, and Greg (a Nauticus technician) replied: "The tabs will work on your boat and I have attached some examples of the installation. They aren’t you exact boat but...

    Effect of bubbles in fiberglass?

    Hi, I've read in several places that the presence of bubbles is bad in newly laid fiberglass. What problems do bubbles cause, and do they always need to be ground out and re-done? Thanks, Jim

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider OK, here are some pictures. First pic shows what I think is fiberglass ground down to the hull (right side of arrows). I think the stuff to the left of the arrows may be leftover peanut butter from the old transom. I am assuming I need to...

    Preventative maintenance while engine and outdrive are pulled

    Hi all, my engine and outdrive are spending the winter in my garage while I'm fixing my transom and deck. I don't know if I'll be able to do much fiberglassing once it gets cold, but I would like to use that down time to do any preventative maintenance I can (or to gather the stuff needed for...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider Got most of the transom core out this weekend. This is what it looked like when I first starting tearing into it: On interesting thing I found was that, rather than being a single plate, the transom core had double layer of plywood lying...

    Engine mount lag screw broke - how to remove?

    I pulled the engine out my I/O a few weeks ago. The lag screws used were apparently not stainless steel, as they were somewhat corroded and very difficult to loosen. One of the screws snapped, leaving a 1/2" stub sticking out of the motor mount. This is what it looks like: I tried a couple of...

    Costs of gel coat/snap-in carpet vs. glued carpet?

    I'm replacing the deck in my 18.5' bowrider, and I'm trying to decide between using glued-in carpet vs. gel-coating the deck and using snap-in carpet. (The family has informed me they want some sort of carpeting surface.) Has anyone recently compared costs for these two options? I figure the...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider Cut out the engineered stringers in the back of the boat in preparation of removing the transom. I have to say, this was about the scariest thing I've done during this restoration. Cutting so close to the hull with the Sawzall was unnerving...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider I've removed more decking and foam until I've found dry foam. Interestingly, the foam in the middle section of the boat (esp. on the port side) was much more wet than the foam in the aft sections. It almost looks like any water that enters...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider And here is a good news/bad news discovery, I think... I'm continuing to remove decking a foot or two at a time, moving fore, and pulling out foam. Tonight, I cut about two feet of decking out (moving toward the front of the boat) and I...
