    hull trueing

    Is It Necessary To True The Whole Length Of The Hull Or Just The Section That Is Used When On The Plain?

    Just the area that is on plane. Most people focus on the last 30" of the hull. Do a search and you will find detailed instructions on this.

    If you have a GPR that is a pre 05, order the 05 and newer ride plate and pump shoe inserts and you will be glad that you did.

    I am refering to the inserts in the hull. The pre 05 boats just have a single insert that is epoxied in the hull and they will spin and cause you a BIG headache. Go to boats.net and look up the ones for the 05 GPR and order them. Look in the FAQ section at the tunnel reinforcement thread and look at all of the pictures and you will see what I'm talking about.

    Jeffsntx is correct, I went through that hassle. I upgraded to the 06 inserts and feel more at ease.

    The '04 GPR uses the same hull insert as the '05 GPR for the pump shoe. The part number is F1G-U8571-00-00. I'm in the middle of adding carbon fiber to the pump tunnel of an '04 GPR and I just took out the pump shoe inserts (removing the green glob is a pain). Since they got a little beat up on the way out, I'm buying a couple of more from boats.net.

    the best way i have found to remove those brackets is to back out the bolt a few turn (all of them) and tap it with a 5lb sledge hammer and they come off really easy! done it on four ski, all came apart really easy!

    Don't worry, the new style inserts are on the 04 already.
