Project Tsunami started

1bayouboy · #1 09-06-2006, 08:19 PM

The boat I bought and brought home last week is a '74 Tsunami with a Stainless Marine twin bracket with '89 150 Yamahas with almost no steering arms left. It's on blocks now and awaiting being stripped down. I plan a hull up refurb and have looked at several of the projects on this site. I'll post some photos once I get a web site to put them on. The boat was originally an I/O and I'm not too confident of the transom job after seeing it. The floor isn't too soft but has a lot of cracks. Has anyone ever pulled the cap off a Sceptre???

Is there is any need to raise the floor on the 23 as seems to be standard procedure on the 20s??

I have a 23 CC and I see no reason why to raise the floors on the 23’s but with twins I would want to re direct the scuppers to out the back of the transom instead of through the deck to the bottom of the hull. If that is the original transom than that would need to be redone and for the cracks in the deck if there are a lot and water has been permitted to get in the lamination that balsa wood will decay and need to be replaced as well. Most cracks are the visible sign that the lamination has already decayed.

Thanks for the reply Fellowship....I will be using a bracket and twins....not sure if I'll be keeping the current aluminum bracket of going to the seamark bracket.
Engine choices are 135 optis (but don't like the no charging at idle), 140 'zukes (worried about the weight), 150 Yam HPDIs or 150 E-Tecs (cost...) Since I'm going to strip it completely I may as well put it back together in the bast possible way. Anything I should look for in the stringers...??? I plan on some sample drillings to see how the foam looks. I like the original glove box door with TSUNAMI on it. The teak cabin doors are in good shape too.

Ha 1bayouboy

As for the bracket the make is a personal choice but you do want enough flotation in the bracket to handle your twins. Most of the motors out there now a days are pretty good but weight could be a issue I would stay with 4 cylinder each and try to keep it as light as poss. As for the stringers they are foam filled so you can drill a couple of holes in them and plug them up later. Most of us have not found much problems in the stringers. But the transoms have been a real issue in all older boats due to the plywood getting rotten.
Good luck

Is that top pix the way the boat sit's at your house now?

If so consider buying some "real" boat stand's.
Call it a life insurance policy.

Thanks Warthog.....no worries.....I have stands coming
and the boat is solidly blocked anyway.....that shot was right after we slid it off the trailer. I believe in overkill on on the life insurance things....

Thanks Warthog.....stands are coming and the boat is solidly blocked as well. The pix was right after we slid it off the trailer.

Looking forward to hearing about your project. I have a 1974 23' Tsunami with a single 235 o/b mounted on the original transom. Love the boat and get complements often. No need to raise the cockpit sole, its perfect as is.
Best regards,

Yes, you can take the cap off. The forward section is very heavy. I would suggest you brace it before lifting.

I only lifted mine, never did pull it clear of the boat to turn it over. Here are some pictures:
