GPS top speed of the WETTE VETTE
I beat the rain here on Saturday morning and took the boat out for the first time this season. The Nordskog GPS speedo I installed this winter worked flawlessly and is pretty cool. The boat also ran great. The GPS reported 97.8 mph at 6300 rpm!!!
This is 2 mph better than the best radar speed I have seen. The only engine change I made had to do with the oil level in the pan. I have had a chronic rear main seal leak that drove me crazy the past two years. I have a Dooley 10 qt pan and somehow I screwed up when marking my dipstick and I was running with 11.5 qts. I pulled the pan this winter with it still full of oil and it was pretty obvious there was to much oil. Dooley told me .300 per quart, and I found it is actually .345" per quart. I am now running 8.5 qts. and there is no more leak. Basically I lowered the oil by 1" in the pan!! The oil temp used to come up to 230 on hard runs. This Saturday the oil never got to 200. I think that pretty much tells the story. Less windage and less oil hitting the piston bottoms which means less oil temp. Perhaps this is why the boat gained 2 mph??? What do you guys think?
I will compare the GPS to the Stalker soon.

Wette Vette How does the boat handle in the upper mph range do you get allot of chine walking or anything? I have a 24' sport and when I get into the 70's the nose feels like it drops and starts to chine walk allitle. Might be the shorty drive on the boat so this year I'm going to try the stock one.

The boat doesn't do very well in rough water, but as far as chine walking it does pretty well. If you are losing your bow lift that could be the problem. I did get into some chine walking before I installed hydraulic steering. It gives you the ability to drive through it. If you just sit there and expect to go straight, you will eventually start chine walking and if you don't correct it gets worse and worse. Very small corrections seem to eliminate it from starting. Different props also affect chine walking. What props have you tried?

I'm running a bravo1 4 blader 26" pitch and it's way to small puts the motor on the rev. limiter. I have a latham full hydraulic steering on the boat. I think it might be the shorty drive because I have to trim it out allot like a 4-5 foot rooster tail just to get the bow to come up. I loose allot in slippage I think when it's that trimed. I'm going to try the lower drive maybe it will keep the bow up. I do correct it but can't drive through it when I stop correcting it it comes back immediatly i think it's the bow settling down on me thats the problem. I don't know. just put the motor back in this weekand I will have to try some fine tuning soon.
