Bought this as a project, needs transom and minor glass work around hull. (A few hairline impact cracks, looks like it bounced off a dock a few times!) Deck felt very solid. Decided while the transom is being torn apart, I better take a peek at the stringers. Damn. Previous owner did a nice job...of laying new floor on top of rotton plywood and stringers. Will post pic's soon, so others will see what they are getting into. Basically, 2 layers of 3/4" plywood. 1 of which was saturated. The bottom layer had been cut out and reinstalled so 2 bare 2x6's could be bolted to the rotton stringers, that were only glassed about 2 inches up. I pulled out everything, except for up at the bow which I will finish next weekend. Very hard going under the dash and under the bench seating up front. I have run into 1" thick fiberglass at the edges of original deck, up at the bow. I'll try to follow the actual wood next weekend. This boat only had 2 stringers, nothing else. I will be creating a better design, fiberglassing everything with epoxy. Boat has a nice running 65 HP Merc, the 4 cylinder version, however I have a 150 HP Force with less than 40 hours just waiting. Transom will be beefed up...I tend to over-build things anyway. Will use 3 layers of 3/4" in the transom, with large knee braces 20" apart. I'm looking for close to a 3" transom. As for the weight difference from the 65 horse merc, I figure I pulled out 150 pounds + of soaking wet foam, plus 250 pounds + of soaking wet, rotten plywood. With one less layer of 3/4 on the deck, that reduces a lot of weight as well. I ran the boat last summer, and noticed it was sitting low in the water, wouldn't plane with 3 people onboard. My wife loves the boat, so it's worth the money to restore. Excellent for fishing, just cruising around exploring the many lakes here in Oregon, etc. We don't waterski, so it's perfect.

Note: I did explore the idea of pouring the transom and stringers in Seacast. I have no problem with the concept, I just prefer using time tested techniques. Original stringers were 2x6's. I just happen to have some left over, clear 2x6x16 doug fir decking from 2 years ago, completely dry. Not pressure treated, but treated with something. I'll epoxy them real good and glass them in.

Pictures soon!

You think 3" is too much overkill? I want this thing to be solid with the 150 hp outboard.

Ran into something odd. 4 inches from where the deck meets the bow, the plywood ends...and it looks like fiberglass was inexpensive in 1972. (Picture inside the bow of a trihull, the W shape needed for the plywood.) I'm looking at 1 inch to 1 1/2 inches thick of fiberglass. Well, it's 70% resin, like they cut the plywood short and decided to fill the gap with what was on hand. I want to completely clean the hull, grind everything off....but I may have to leave this as is, and glass my deck to this. Maybe put a few layers of glass over their resin work, to actually give it so,me strength???

Hi there and welcome....

Yep i agree I would cut that in half , 1 1/2 inchs is normal, see 300 hp on 1 1/2 inch transom !! plus when you mount it will only open to what 2 inchs !! I only got a 100 hp merc, but i can stand and also bounce on it and the hole boat moves not the transon !! Just make sure you glass her in really well !!! John

I agree 3" is a bit much.

Okay, I'll go for the 2 inch transom and not go for the overkill :) I'm 45, and this one will be my fishing boat when I retire, so it's getting done right. I'll post pic's this Saturday after I get the remaining crap out of it. Can't stand looking at the hull while there's more to come out. Once you get past that point and you're only looking at putting it together again....it gets very enjoyable. From past experience, I've noticed there's always a rush to get it torn apart....which is no fun, but once things start going together, that's where the enjoyment is. If not for thinking of fishing, I could take years assembling :)

Has it really been 3 years? Wow. Been fishing and having fun! Wife can't handle full speed, have to keep it under 45 mph when she's on board ;-) Biggest problem has been the transponder for the fish finder. It's mounted an inch above the bottom of the keel. At full speed, cruising nicely, I suspect only a half inch of the boat is in the water....as suddenly the alarm goes off saying I'm in shallow water. The first time was heart stopping as I quickly shut down teh motor....then it read 150 feet deep! Took me a minute to figure out what was going on....and calm down!

Oh wow....can't believe it...sold the boat to finance the next project. Well, it'll give the new owner years and years of reliable fishing! I let it go too cheap, but I'm anxious to get started on the new-to-me 1972 Chris Craft Lancer. This madness just doesn't end it seems:)

Perhaps the joy is in working on the restoration after all?
