What kind of fuel consumption do you think an I/O 454 chevy would be at on a 2520? I need a 60-80 mile range each way without killing me on fuel.

What kind of issues should I foresee with an I/O. It is a freshwater closed system.

Any specific I should look for on the boat I am looking to buy?

Thank you.
 
In my opinion that 454 will drink at twice what a 225 or 250 hp 4 stroke O/B will, w/o twice the performance. plus its a lot of weight and maintenance. I would take a wild guess and say at cruise it could burn 15-18 GPH depending on if it is carbureted or injected. If you are concerned about fuel economy the 454 is not the way to go in my opinion for what its worth
 
1 MPG is pretty rough. The owner claims it was getting 6 mpg when he bought it new. I would be happy with 3 mpg. How do the 2520's ride in rough seas. Say 4' seas? Anything specific that I should look for on the boat as concern to problems?
 
6?

No way, not possible.

A very good, fuel efficient boat at cruise would be 2-3.

Most are less than 1-2 at cruise speed.

LOL....Yea Right. NOT! FYI......A 16ft -18ft jon boat with a 40Hp outboard in a River would maybe get 6MPG at cruise.

A 7000lb boat with a carbed BB chevy in it.......No way.

Normal maintenance, as with any I/O system.
Where an outboard requires periodic replacement of the water pump, t-stats, poppet, fuel pumps, filters... an I/O requires maintenance too.
One primary item would be the bellows, because that is what keeps water out of the boat, and it's also an item many times neglected. :shock:

If you decide to go this route, find a yard that has people who specialize in I/O's to maintain it properly.
As for ride... With that big chunk of iron in her belly, she will ride better than an outboard powered boat, but it is likely to have a lower top speed than an outboard boat.

The good news... Marine V-8 motors are way cheaper to replace than an outboard, should the need arise.
Economy measures can also be employed on a marine motor in the same manner as the motor in your truck.
For instance, carburators can be replaced with fuel injection without breaking the bank if you so desire.

Keep in mind that even these motors have unique maintenance requirements.
Water pumps need periodic replacement as do those cooling manifolds.
Even with I/O's and Inboards, there is no free lunch. Of course, there is no free lunch with an outboard either.
Both have unique maintenance requirements that should be adhered to for a long trouble free life.

Good luck!
 
Heck, no diesel would get mpg!

I'd fhugghedabout this boat ... you can't afford to run her ...
 
I went to see the boat today. It has a 7.4Gi 454 Volvo Penta Duo Prop fuel injected from the factory special order. It has 400 hours and seems well maintained. What would be a fair price for a boat in fair to good condition. It is a little rough on the hull side, but not major issues. 1997 2520 DV. Thanks for your help!
