I am looking to get a baseline on how much HP it takes to go a certain MPH in the 18.
CI?
HP?
DRIVE?
PROP?
RPM?
MPH?
Thanks!

ENGINE: 1997 MAG 350 MPI Gen+ (an anomoly of a stock motor)
HP: Rated at 300PSHP, but I think that's conservative
DRIVE: Bravo One 1.65:1 ratio
PROP: Mercury Mirage Plus 25P
RPM: 5100-5200 on VDO Tach
MPH: 70.5-72.0MPH (My Garmin reports between these speeds consistantly)

Good luck Byron - this is probably like asking a fisherman the size of the one that got away :D
Matty beat me to the spreadsheet thought - but here is the LINK (http://www.donzi.net/Reg_boats.html)

That is a nice looking 18, sans glue job. lots of towels and rags will go nicely with all that acetone.

MP,
Thanks for posting the pics!!
Oh yeah...ACETONE :cool: Maybe my girlfriend will volunteer for that job :D I agree, I don't understand why they would ever glue the carpet in :mad: Oh well, that is about the worst thing on the boat. I will also be cleaning up the rigging in the engine compartment. If I have time maybe a bigger 350. I looked up the numbers on the 350 in it and it is an early 70's 350 4 bolt main. Maybe the original?
What are some tips on how to get this thing to run? Besides HP?
Anyone have an interest in the rocket trailer? I am putting it on a tandem Eagle eventually.

Byron,
Mphatc has a Volvo ultra for sale as well.
I might be interested in the trailer. Give me a call tonight and I will tell you about my setup when I ran a volvo.

Damn glad I re-read the post through for a minute I though MP was dragging a sweet water boat South! Ranman did say Ohio but them southern boys have been real active this winter. That SX drive of Marios would be a very nice upgrade.
Bryon the best of luck with your new Toy :)
