Default Fountain and their 48 diesel cruisers

Whats the deal with fountain changing from 480 Yanmars to 480 cummins. The rpms are less I believe 2600 vs 330 on Yanmar but printed speeds appear to be the same. Anybody have any info. Thanks Jeff

Cummins marine engines are Mercruiser Products and Reggie sleeps with Mercury.

the cummins engines with propper headwork and valve springs will turn up just as fast as anyother diesel. These I am sure are in stock merc/cummins configuration and have not hot-rodding to them at all, but they definately have potential.

What caught my eye was their claim to a "World Record", Key West to Cancun. 405 miles in 8 hrs, 36 minutes. Anyone know who would have sanctioned or verified that claim. APBA/UIM has set rules for such long distance runs in the past. Did they or some other recognized body verify Fountains claim?

I don't understand tripples in boats like this, why not bigger twins. It just doesn't make sense to have 3 props when 2 can counter rotate... and also you end up buying a 3rd engine.

The article did mention about the boat able to plane on 2 motors. With trips would it not plane better..Also with larger twins the rpms are usually alot less, more weight and so on.

Default 48 Fountain with Cummins/MerCruiser diesels

Hi Jeff,

Mercury (Brunswick) holds a significant stock position in Fountain Powerboats, hence the understandable switch.
The tradeoff for lower RPMs is higher torque with the Cummins.

The run to Mexico was done with Eric Colby on board (Boating magazine, good guy and a straight shooter) and was done at least two years ago, maybe three?

As to three engines V two. Having owned a performance boat with three engines, it's hard to drop back to two. Acceleration, reliability, endurance are all (generally) increased with three engines. Ironically operating expense isn't that much more. The 48's primarily had surface drives.

Glad you're well jeff, and the past hurricane season gave you and us a break!

Steve
