Re: Larson Shark **All Years** trihull boat
Based on the research I've done (found a couple of old Larson catalogs from 1974), I believe mine has the original engine. The boat is titled as a 1974, but beyond that, I'm not sure how you'd validate the age on yours. Might be able to decode the hull number.
I posted some better pictures on Flickr.
You can see all of them here. Here are a few:
Transom is pretty sketchy
As you can see, the transom is probably the worst part of the boat. It has a little bit of flex to it but seems fairly sturdy. I'm just not doing anything crazy (skiing/tubing/etc.) with the boat until I can get in and put a new transom in, which might happen this winter. In the meantime, I just go easy on it and keep an eye on things.
I recently removed the stock canopy and replaced it with a tall bimini top. I still have the stock one and could probably ship it to you for the price of shipping if you want it. Not sure how it would work for shipping the long pieces of the frame, but it might be doable, plus it looks like your boat already has the rails and snaps in place to hold everything up. Send me a PM if you're interested.
