Re: re-powering a WHALER 31, made in the late eighties for a few years. I am thinking about purchasing one that had gas power and changing over to diesel. Any idea what kind of mileage the diesel-powered boat got? Thanks

You ought to read what Pascoe has to say about diesel vs gasoline engines.

I am currently repowering with two Marine Max diesels. They are based on the [AM General] Hummer block and are direct drop ins for replacing GM 350 or 454 gassers. They develop 275-HP with around 450-FT-LBS torque at low end. Currently I have 7.4-liter fuel injected Crusaders. I should improve performance at crusing with larger props, 20x23, as well as cut fuel consumption fifty perecent.

Sounds like you have these engines:

After reading Pascoe's myths about diesel engines, I must say that I disagree with him on all points.
I find the information that Pascoe has provided is misleading, at best.

Frostbite is right on. That article is full of misinformation. It would be a shame for anyone considering a repower to think that is an accurate comparison.

My main question is this:
If I buy a new Dodge pickup with a cummins diesel it is a $4500 option. Why does that SAME engine "marinized" cost $40,000 as an option? There CAN'T be $35,000 in upgrades.

The 89"s came with Cummins 250's - - not enough power..The 300's will give you all the speed you need and consumption of about 1.5 miles to the gallon @2250 rpm.. You'll cruise at 24 knots all day long.....a little noisy, but, you'll have a great boat..good luck

Could you guys elaborate a little on the specifics of why you disagree with the article? It would be enlightening. Thakns.

Pascoe makes blanket statements and qualifies the statements with bits of fact that aren't always relevant.
Myth #1-Diesel is safer than gas.
Myth #2,4,5, Essentially the same
Myth #3 Diesels are more economical.
In real life I don't think you will find many people yanking their diesel engines to replace them with gasoline powered ones.
Thats my slanted view chief, we welcome yours.
