    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider This is the spot on the port side of the boat, looking up at the underside of the rear platform. The port gunwhale is to the right, the midline of the boat is to the left (out of frame) and the rear of the boat is at the bottom of the...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider Thanks, guys. The only thing slowing me down now is the weather. Supposed to be cold and maybe even a bit snowy here for at least the next week. Might see a day or two in the 40s, but it's supposed to hit the teens tonight. Anyway...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider Feels like a milestone of sorts tonight. After gelcoating the bilge and transom core this weekend... I drilled holes in the transom for the outdrive and test-fitted the gimbal housing. It fit like a dream! The holes lined up with the...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider I'm not going to say I'm done grinding, because every time I think I've finished with the grinder, I find that there's more to do! Anyway, I finished cleaning up the edges of the ski locker, bilge and access panel to the fuel sender, and I...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider I finished fiberglassing the deck today. I had faired the deck a couple of days ago, and yesterday I sanded it smooth. Sanding was not fun... the fairing compound was not waxed, so it was really gummy when trying to sand. I ended up using an...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider Pedestal seat bases are installed and glassed in. The deck needs the final layer of 6 oz. still, but that's about it. I will be glad to finish the fiberglassing. Driver side pedestal base with one layer of 1708: Both pedestal bases in...

    Tools help.

    Re: Tools help. I agree with the full face respirator. Mine only covers nose and mouth, and after a while, it gets rather uncomfortable to wear. I have two types of masks. For grinding, I have a simple 3M mask with replaceable filters: Replacement filters are very cheap, so it's not a big...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider Sorry, I wasn't too clear in describing it, I think. The aluminum flange is part of the cover for the ski locker: The boat didn't come with any sort of flange around the opening in the deck itself. I've tried searching iboats.com to see...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider The ski locker on this boat is just a hole cut in the deck that has a cover that fits into the hole. The cover has an aluminum flange that allows the cover to sit flush to the floor, but the hole in the deck is just that: a hole with no trim...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider And here's the round base. (It also would flare in on a 45 degree angle, but I didn't draw that in. Just imagine a line about one and half inches in from the perimeter to picture the size of the upper surface.) What do you all think? I...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider Let's try this again... Still trying to figure out these seat bases. I cut a couple of different bases out of pink foam board to see how they might look. One is round, with a diameter of 16"; the other is square with 14" sides. Both have...

    Is it worth it? '98 Larson 5.7GS DP Lower Transom Rot

    Re: Is it worth it? '98 Larson 5.7GS DP Lower Transom Rot HF, I had the same reaction. The staples did make removal easier, but i can't believe they added much strength. For removing the good part of the transom shield, I did just as rickryder suggests: I set my saw depth a bit shallower than...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider Here's what it looks like with everything PB'd back in. I think I'll need to do another pass with some more PB. I think some additional filling will be needed. Even so, I'm happy to get the foam in. I was surprised how little foam I...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider Had a hard time getting the garage warm enough for foaming. Eventually I decided to cover the boat and put a space heater under the cover. That did the trick! I got the boat up to 85 degrees, and a small fan blew air into the hull cavities...

    Transom problems with Larson 186 SEI I/O Bowrider

    Re: Transom problems with Larson 186 SEI I/O Bowrider And here we are with the deck tabbed in and the seams filled with peanut butter: Question: in the original design, the edges of the deck around the motor enclosure/bilge (see picture below) were not tabbed to the bilge tray; they were...

    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...
