When you painted it, the GPS had a harder time seeing you so it thought you were running faster, you gotta strip it back down to get a real accurate comparison!

MM Brand: 2007 Prodrive 36 Boat Brand: My own personnel build Boat Size: 17'10 x 48" square chine with double taper transom Boat Layout: open/ drive seat box and built in 15 gal fuel tank up front as step to front deck Old Hull - all 1/8" 1 piece hull, with 1/8 tread plate false floor, 5' front deck, open floor plan. New Hull - 3/16 bottom, 1/8" sides, .100 false floor and front deck, drivers console, 15 gal built in tank up front and open floor plan. Speed test with Old Hull 19'10" x 50": Stock 36 PD on old hull (19'10" x 50") Deep Water - 25 mph 36 PD SETX heads and custom built exhaust, no baffles Deep Water - 28 mph 36 PD, SETX heads, SETX cam and exhaust Deep Water - 30 mph Fulled loaded to the gills with shit - 27.8 mph Speed Test with new 17'10" x 48" IMG_2522.JPG IMG_2523.JPG IMG_2528.JPG 36 PD, SETX Heads, SETX cam and exhaust with stock carb, boat unpainted Deep water - 30 mph 36 PD SETX heads, SETX cam and exhaust with modded stock carb (ported, shafts shaved down, jetted, all work done by Preston), boat unpainted Deep Water - 32.2 Deep Water loaded to the gills going to the camp - 30.1 36 PD SETX heads, SETX cam and exhaust with Mikuni HSR42, Gator Glide and painted Duck Boat Drab Deep Water - 34.2 The final speed test was performed in a very windy day. No speed change from running with or against the wind. My boat began to porpoise when I tried to trim up. I had very little fuel in my front tank which helps this and I may still need to shift my battery up front. But at 34.2 MPH, my stock prop is completely buried, no roost at all. And I mean at all, no spray. If I tried to trim up, it would start to bounce. I plan on doing some more runs this week moving weight around to trim up and let it eat some more. The motor is still pulling really strong eben with it completely buried. My tach was acting up so I don't have the rpm's, but I have it working now. Will post the new speeds and rpms this week. I see no reason why it won't do 35 mph. So basically going from a bone stock 36 PD to a stage 2 gave me roughly 10 MPH increase and a hell of lot more load carring capacity. |

Well my test run with all the fuel didn't change shit. Still bouncing, and thats with 15 gal of fuel up front and wedges under the hull in the back. IMG_2566[1].JPG After talking to a few guys, it looks like I'm gonna have to box the transom off and leave about 1" - 1.5" of tab out the back all the way across as a trim tab. The hull didn't bounce a lick before a few mods. I guess the extra top end speen has pushed me over the stability level of the hull with this transom taper. But opening morn is Sat so that shit will have to wait. Plus durning hunting season, my shit is loaded to the gills so I'll have enough weight in it to move around to help out. But 34 with prop buried aint bad..................... for now.

good lookin boat man wish i had the skills to build my own Dfou Just out of curiosity, what about the rake would effect the porpoising? would it be because the rake is too long or short? |

Actually found the problem, boat doesn't like the transom angle. IMG_2568.JPG IMG_2569.JPG IMG_2571.JPG Used a 2' level to insure it was the same as the bottom of hull so it would weld straight. removed the wedges from the bottom also. Cleaned it up, painted it. Totally different boat now. I did have to grind off the gator glide to make the mod, but it didn't effect shit this pass weekend. And I also though the 1" tab across would get hung up also with all the grass and lillies on our lease. Nope. Right now the tab is completely straight out, didn't bend it one way or the other. One thing I did notice this weekend was that when my boat was completely empty and I had less than 1/4 tank, it would just start to bounce. Very little. I just need to tweek the tab a little to get it to run right with low fuel and no load. Seems to get up a little quicker also. |

And you did all that to stop it from bouncing at 34 mph while the boat was empty? |
