Thought I would take a minute to update this thread. After 4 weeks of tweaking drive height, that's another story posted in another thread. The boat ran a solid 92 mph in it's every day trim. Leo told me the best he had BEFORE he switched to the Bmax's was 94 mph. There is probably a little more in the boat, but for now I'm good with 92.

That's hauling the mail!!!!

good results but something is still off....the navy hull in California runs 100 with stock Merc 700/NXT's. My buddy Oliver had the black hull (former OSO boat, then fastfinance.com, then submarine, national liquidators boat) and knows every 38 Danny built. He drove the Merc. 700 boat in Lake Mead and saw the 100 tick by....he has been on Leo's boat and has had the boat on his lift in N. Palm Beach a few times.

Do the Bmax's rob that much HP?

I know the Bmax's do rob some power, but how much I don't know. From what I read most are losing 2-3mph when changing from the XR's. The best setup I found was with the propshaft depth of 3.5". The setup is different with the 1.3 gears. I might be faster with a slightly higher propshaft depth and 5 blade props, but it wouldn't be by that much and drive reliability would definitely suffer. The changes I made netted almost 4 mph and got me fresh drives at the same time. I would love to get some specifics on the setup of some of the other 38's. For right now I'm satisfied with the boats perfomance, but I'm sure over time more changes will be in order. We all know that the need for speed is a never ending process.

JMS322 did you change over to the 1.5 gears?

Yes, here is the thread about some of my testing http://www.offshoreonly.com/forums/d...ng-advise.html

Little update on the "No Life Like It" 38.... Port engine supposedly fairly fresh when I got the boat (15 hours) was built by a HACK. Starboard engine was done by Chief and had 3 hours on it when I got the boat. It checks out fine. After noticing some oil pressure fluctuations, I decided to have the port engine pulled to take a look. We found two wrist pin spiral locks in the oil pan. Fortunately caught the problem before it exploded. Complete rebuild is just about complete and should be back on the water this week. The quality of workmanship left a lot to be desired. This time it is built right and hopefully we'll pickup a few mph. I'll post some results after I get it broke in.

Oh man. Glad you caught it. Let us know how she runs!

Good catch, John! Keep us posted.

John,
You dont get any closer than that! Good call on pulling it and having it checked out!!! Glad to hear you're almost back in the water... :cool:
