jack plate question
i got this jack plate when i bought my viper. i am planning on replaceing the manual plate on the virage with it. i dont have a pump and was wondering if any pump from a hydrulic supply store would work, and how much psi it will need? ive also included a couple of pics of the viper with the new transom. iv got the core material, just haveing too much fun with the virage to even think about the viper.

Re: jack plate question
i also read some where the stage 2 hull runs best with 8 inches of set back. this plate is only 5 1/2. would it be worth modifying it before i install it? is the extra 2 1/2 inches worth it?

Re: jack plate question
Just install a setback bracket between the jack plate and the hull. I have a 10" setback (rapid jack) and a 4" hyd. lift behind it. Works great.

Re: jack plate question
Hydraulic pressure is force over area, or weight you want to lift over square inch displacement of your hydraulic cylinder. Just figure out total weight of engine and related parts over cylinder displacement (pi R squared....), this will give you minimum psi needed to lift

Re: jack plate question

Re: jack plate question
I'm not real familiar with that motor, but if it is heavy, the more you set it back, the more it will want to swamp the boat..
