Old school because I can't afford new things plus I know how to work on the older motors.
It's a 1980's "Centurion" picklefork (sp?) 10 foot boat. It's a very stout hull that has a disclaimer as being a "Race Boat" from the factory on it. It came with a 30 hp Johnson which was fun for a while but now I've stepped up the plate. We now have a 1974 (I think) 85 HP Inline 4 Merc sittin on the back. We took her out yesterday and gave it a test run, we slowly let it off the trailor and she sits respectively in the water. We don't have the tilt and trim setup on it yet so we are dealing with the pin for our tilt and had it set at 1 notch away from the bottom. First launch and the boat came up more than 45 degrees no joke. Put the pin all the way down so the motor is tucked up as far as it can to the boat. Tried it again and she jumps out of the hole. So once on plain it starts hopping perty good. NOTE we have the battery on the front left with the gas tank basically in the center of the boat. Up to this point everythings seems as though it could be ironed out. My problem is this
Once on plain and basically just cruising I hit the gas boat accelerates like a raped ape BUT it has TOO much torque. The boat rolls over to the left side and the left sponson digs in. to correct this I plan on mounting the gas tank as far to the front as I can along with moving the battery to the right side of the boat. Now my only other ideas to correct this would be to put weight on the right side (possibly like a sand bag in the far front right) and possibly those trim tabs on the back. Would this help? Anybody got ANY suggestions? I need help. I would like to hit a respectible 60 mph and think I would be able to w\this hull design and power. Any ideas?????
