Starting a 1974 Tri-Hull Restoration, it's a Stryker Mark IV model. Need help with any information or an owners manual.

Hoping you got the water resistant stuff. And you did thru bolt the fishing seat?

OSB gets wet then crumbles without being sealed thoroughly ! Did you check structure for wood rot ?

I put on the OSB for the front decking only, that's my only sheet of OSB, the rest is 3/4" plywood siding I slapped down into the outline of the flooring but it's sealed bottom and top entirely before being screwed in and resealed each screw in with more resin to create better water tight seals. Anything on the sides of the boat has been sealed with a Marine Sealant designed for below the waterline so it won't mildew or rot away. I made sure there won't be a single water intrusion and after having it on the water just floating for about 2hrs when first testing it. Once I get the engine running I'll be putting all the weight on it and taking it back out to make sure the job I've done will last as long as I need it to before I decide to do something new with it or whatever. It definitely won't stay this style forever but I'm keeping it as a TriHull

And to add to it, the flooring in the boat was done in two parts so I could make sure the area closer to the bow has less of a chance to leak water through it. I have much more floatation foam in my two Poons on the sides and towards the back as theres barely any weight in the front. As I've said before it's not professional but it's pretty damn good for an amateur

I did, while some areas looked slightly more concerning than other, after nights of research and having the cap off for about 3 weeks, I inspected stringer and when I through the holes through for the motor bolts, I was able to check the status of the transom and it was all passable until I decide I want to redo it for shits and giggles to do it myself.

Through bolted, drilled the pilot holes and used a small detail brush to seal the insides before feeding the bolts through and sealing the outer rim base of the seats to stop water from leaking in. Any holes drilled for wires got sealed up as well

Well, it appears you have a well thought out redneck frankenstien boat. Enjoy.

It's quite the freak of nature, but when I get more settled and comfortable in life I'll take the time to truly restore it back the way it used to be after taking it apart again
