I just wanted to make a post to all you about how my setup and changes have worked out for me and the history I've had with these boats.
First off, the Hull is an 87 20.8 Lavey Craft Mod-V tunnel hull. As far as I know, this is one of six made that has this top- with the wind screen. My dad first got one about 10 years ago on a trade and I later bought the yellow one as seen in the pictures.
In 2011, we had a fire at the house where we stored the boats and both boats completely burned, it was a sad loss. Then a couple years ago, I saw this one (black) pop up for sale and I knew I had to buy it, despite already having bought a Daytona.
Up until now the boat had a really nice small block and alpha SS drive, it had a 406 with aluminum heads, 11:1 comp, 950cfm carb and the boat ran really nice at about 95mph. Although, the previous owner wasn't huge on boats, he did run nitrous in his small block and claimed it ran over 100 easily.
Now when I got it, I could tell right away the motor was getting tired... It needed a rewind however I got to thinking that I had an almost brand new rebuilt 509 bbc, merlin block and heads at about 10:1 and tunnel ram sitting around. I decided the mouse motor was nice, but would be much nicer to throw in the big block.
Upon doing all this, I knew I would need to change the alpha out, (didn't know it was an SS at the time) but went and bought a bravo gimbal setup because I had a bravo sitting around. Finally, I got the big block installed, gimbals swapped, added oil cooler, and rewired the entire boat; 'It was time to try it. I knew it wasn't going to run really fast or much faster than the small block did- the big block motor is nothing special- something around 600hp give or take and the small block was probably 550 or so and a lot lighter.
I took the boat out and best number I saw was around the 90mph mark. I got to thinking, I happen to have 2 black hawks sitting around that I got online a few years ago, what if I put one of those on.
When I went to do that they were both broken and in need of help. I couldn't even make a test run without risking shattering them. I called up Aaron at Max Machine Works, told him what I had, and told him that I just wanted to get one of the 2 drives I had fixed and have it setup to run a single bravo style prop. At which point they hooked it up, made custom spacers for the single prop and got the inside all dialed in and upgraded to the latest and greatest with much beefier bearings and shafts and taller 1.35 ratios over the 1.5 the bravo had.
Just a couple weeks ago I got it all installed decided to run the same exact prop that I ran on the bravo, a 25p Revolution 4. First time out I cannot explain the difference it made, boat honestly felt like a completely new one. After cruising around getting to know the new feel I decided to make a pass... the thing ran 112mph @ 7300 rpm, Yes that's too high and I need to work on the prop situation but I picked up about 22mph with the same motor, timing, prop, everything! Not a thing was touched except the drive. On top of all that I don't even have the right prop on it yet! Anyways, kind of long to read, but I was blown away at how well it worked and wanted to give Max a shout out for being the only guys that can really do not only what I wanted but what I really needed. They know what works!
