sounds like a good reason for 500+ hp

Some airboats have the LSA motors in them. Also some jet power boats use LSA motors

Kodiak Marine aka KEM builds marine LS motors and have done a few LSA motors.

also Marine Power has a drop in complete marine LSA engine package 557 hp.

also Mast can do this version.

Volvo Penta has their GM LS - 6.0L 380 hp and 430 hp cat motors nothing wrong with them and their drives are better compared to the Merc Alpha and Merc Bravo III. I would rather have the new Volvo SX drive than the plain Merc Bravo I if you have some hp in front of it. Also look for Volvo to step up into the 500 + hp range soon.

IMO, which is near worth nothing, I like the idea of BB Merc. HP, turn key, warranty, sellable or saleable defintely not "sailable", sorry for my lack of grammar and spelling, english is tough. Also as a second the twin smal blocks might be a lot of fun and still all of the above. That rig would be something like "wave hippy" would it not ? , Doug or anyone please elaborate on the pro's and con's of weight verses power and speed as well as cost to operate of the BB-HP single verses the twin SB's. I would think getting around the marina and docking would be easier with the twins ?

This boat will be set up for twins. Stock BB Mercs (380 HP) will run 78 MPH. To do that with a single you need serious power and a drive to match. Twin Merc 520 HP should run 90 with a 2 year warrenty.

Chris, you need to stop by and check out this build!!

best regards, Doug

The new 520's are almost a no brainer with the lower price and 2 year wrnty!

Thanks for all the updates!

The graphics are looking good, not perfect yet IMO but flashy enough and will still look newer in 10 years is very important!

I am stopping by the shop Tuesday! I am all for reliable big power! I think the new 520's in this boat would be the ticket!

what power is needed to run 100mph?

28 with 700 Cobra's and Bravo's 100+ :eekdrop: [ATTACH=CONFIG]507704[/ATTACH]

28 with twin 650 Contenders and SSM #5's 100+ :D [ATTACH=CONFIG]507705[/ATTACH]

well doug, looks like a twin to no excuses is the best bet then. serious question, why would a boat run faster with no. 5's than bravos?
