OB 15

Post by CraigLam » Mon Sep 19, 2011 12:43 am

I want to update, so I hope this is the way on this thread. The Bearcat 55 restoration is progressing well. Big question. What's the big difference in resins. I know that West system is good. What about just regular resin. Regular resin is about $35.00 around town. West System is about $100.00! :doh: Couldn't I just use regular resin for my boat?

Not gonna be a problem. People overpower these boats all the time, but JM designs them light and strong and then under-rates them so you're fine :D

If you're worried about it just put an extra layer of biax on the transom or a little stronger knees, but I'd think it will be fine just as designed 8)

I think you'll find AdamG is running a 70 hp on his OB15, I'd say the weight would be the thing to look at... if you think it is not too heavy, go for it.

Well, it's really only a 60, but it would be a 70 with the 70 carb on it, more or less. Still, it can take the HP so long as you beef up the transom and the transom braces a bit. Just don't get crazy with radical turns while under full throttle.

I'm wondering, with a restored Bearcat 55 with WOT, on the back of an OB 15, what would be top speed at WOT would be. Some say 25 mph. I know there is alot of factors involved. I had an old 59 Merlin with a 40 h.p. Johnson and that did 30 mph. I would think a 60 h.p. engine would do alot faster. One of the reasons I picked the OB 15' Skiff was the h.p. rating (50h.p.). Well, I'll tell ya, once I put her in the water with WOT - I'll let ya know. :wink:

I'm not sure what it'll be, but I'll bet you that it's well above 25MPH. :wink:

With my 60, I'm getting close to 40mph, but not quite there yet. The drag of the hull seems to be reaching a practical limit.

My OB 15 had a 40hp mariner. When it ran right it did 35mph. Really great boat. I wish I had kept it and powered it with a new 40 or 50. Good luck!

Hi, everybody. I'm over here now. I guess I'm stuck with OB 15. I think the OB can stand for "Old Bearcat". Anyway, I worked on the motor today and had a lot of godd luck with the results.
