Question For Jo
Jo I have another one or your boats. We used it last weekend and are probably done for the year. While running I have to run the tabs at a little over 3 to stop the porposing, that is at a cruising speed. I think it is over propped some because I am only able to turn around 4200-4300 rpm and I am guessing from what Neversatisfied said that at those rpm's I am doing between 70-75 ish. He was running beside us. I don't know what size props they are yet because I have not been able to get them off. Previous owner said he never took them off. Anyways, Jo any ideas on getting it to stop porposing so bad? I am planing on atleast a new back seat this winter, and a cover, maybe a whole new interior. It also needs some carb work.

Hi Dale,
I am glad you purchased another Pantera 28' Twin. My Father sold your 28' back in 1986 as a hull and deck only with upholstery and hardware. He did not rig it. I was 15 years old at the time so I do not have much info. to offer you.
I would need to see pictures of your set up and props to give you better advice. Are the props spinning in or out ? Does it do it when the drives are tucked in all the way or when trimmed ? How much fuel was in the tank ?
When you deal with speedmaster drives and props the set up is quite different than Bravo 1 drives and 4 blade bravo 1 props on your other Pantera 28'. It seems to me that your RPM is down from where it needs to be.
Call Dave at MDG Performance in Maryland since I think he worked on that 28' of yours while stored at his Marina. Dave is a very experienced engine builder with many years of experience.

Jo, it does it wether drives are in or out. The props are spinning out. The higher the rpm the less tab needed, and I understand that. The tank was full when we started. I was just wondering if there was something I could do to not have to use so much tab at lower rpms?
As far as rpm's being down, I think the props might be a little big. The motors were checked out and were fine with 150lbs on every cylinder.

bigboat - add more power!
Not even kidding. I think that combo needs a bit more power to run right. The hull is trying to work but doesnt have the umph to get there. In the meantime grab a real small set of props just to let the motor buzz up a bit easier. Should change the attitude of the boat a bunch. Just my .02.
