Picked up this Tristar over the weekend, very nice unmolested boat. PO had the boat ten years after purchasing from the original owner. PO said motor ingested water at the end of 2011 and has been sitting since. He removed the plugs, got the water out, & soaked the cylinders w/ oil etc. I have the motor out but have not torn it down yet. It appears that all starboard cylinders got water. I split the manifold and riser and it looked fine, they're only two years old. Not sure about a head gasket cause wouldn't that trash just two adjoinig cylinders? PO had the intake off in 2011 to replace a noisy lifter, he thinks the intake bolts weren't tight enough and thats how the water got in there? Not so sure about that one. Anything I should look for as I tear down the motor? Thanks

I've got an almost identical '88 Tristar, dark blue version, 620 hours or so. You're interior looks to be in great shape. My motor has been very durable, although I did have one of the heads develop a leak at #8. I've since replaced heads with GT-40's. I still have both of the old heads, one of which is still in great condition. If you find that you just need one head, it's yours for the cost of shipping.
The horiz. stripe at the water line isn't original (least I've never seen one that way).
The trailer looks identical to mine (built by SMP). As evident by your pictures, the carpet wrapped plywood on the steps and front is causing you some rust issues, I've removed mine and welded in some new metal at the rear step.
Not sure that I can offer a diagnosis on the point of origin of the engine water. Any engine pics?
Sweet ride though, we enjoy ours. I think you will too.
