Possible Boat Problems

[RIPNITZ]

Hello everyone, another new guy here! I recently obtained a second boat, a 1969 Glassmaster Trihull- 70 (or 75) hp Evinrude. The individual I purchased it from pulled up the carpet and floor to check the stringers but the sprayed that canned foam mess from lowes all around the stringers basically filling up the hull.

My main question is when i get the boat to at least 10 mph, the bow rises way to high. My guess is from all the foam. Should I cut it out? And also around the same speed the hull if making a popping almost a cracking sound when going over choppy waters. Any advice would be wonderful.

Thanks In Advance, And I love this forum!! I will attempt to post pics as soon as I figure out how.

Re: Possible Boat Problems

foam would not cause that problem. the angle of the motor, and the load in the boat would do that. there is a tilt pin that can be move closer to the transom. get the model # off the motor. you really need to know what you have.

Re: Possible Boat Problems

You are correct, there is a tilt pin and I will try adjusting that. As far as the cracking/ popping sound, the hull and transom appears to be in good condition considering the age. I didnt know if it was caused by the foam expanding. But I will take a closer look tonight or tomorrow afternoon. And I really appreciate the quick response.

Re: Possible Boat Problems

Probably the foam creaking/popping/breaking as the hull flexes.

Many thanks to tashasdaddy and tmcalavy for your assistance! I moved the pin closer to the transom and had her running 40 mph with no problem. And the popping/ cracking sound I heard was simply the plywood rubbing against the foam between the stringers. Very simple fix, thanks to your help.
