You can have both. IMCO has a dual drive gear splitter for a single engine. You'll need more than a 525 though unless the boat is under 28' or so.

I think DCB is actually doing something with that.... either in an M31 or F32.. not sure which model......

Don't think it would be the M31 as it's a true tunnel cat.

never seen a 30' performance cat with a single but i would suspect u could end up looking like a fool around the docks vs. a hero with some egg beaters on back.

You don't remember the 30' Cobra Terminators built by Peter Casini in NJ? I think they won two WCs with single engines back in the day. I'm sure there are guys here who have raced them or had them for pleasureboats.

should have said been in one...but. point is; it's far less than optimal for an offshore boat with todays knowledge and technology.

In my opinion...any thing beyond 24' deep v for offshore you go twins....just can't build enough reliable torque with a single.

Having both props working for you in the rough stuff makes a difference.

HUH???? Maybe in older heavier boats, but hardly any boats less than 28' even come with twins I/O's anymore.

They have made only a few of them and the one in the 35 Nordic kept having issues from what I was told.

How about a single merc 1350 and a #8 drive in a DCB 32?

UD

Weismann Marine is developing a twin prop surface drive that they rate at up to 1500hp. That will stop torque steer common to single engine boats.

Thats great, now take a 30 predator or 30 Spectre with some decent small blocks in it, and that pretty boat with 600 lbs of gel on it will get spanked :D Especially in rough water

I couldn't agree more! A nice 30-32 foot Cat with 300XS motors and you would have a 100MPH boat that kicks azz all day long. Plus, you can run it at 100MPH all day with decent fuel consumption [far better than any other engine]. If your cruising you will get about 2.1 to 2.4 MPG.

I agree twin outboards are a bullet proof combination coupled with a 2 year warranty on the motors....with an optional additional 2 year extended plan. You then have 4 years of warrantied motors and you can drive it like you stole it:).

Well you take a 30-32ft Outboard powered boat and you will spank those small blocks like a White House intern. Plus, those high reving small blocks drink the fuel and never last like a BBC.:evilb:

P.S. Always makes me laugh when we smoke a big twin engine boat with our little 28ft Howard Sportdeck:drink:.

Love wackers.

Curious without any closed loop cooling - when does salt water corrosion kill them in terms of years?

Uncle Dave

A 30ft boat needs twins, period. No free lunches with a single engine. The money you spend on a high hp single will catch up fast to what it will cost to run twin stock power.......
