HPX 15 with 50HP?

Recommended Posts

I know it's a long shot, but I'm wondering if any of you guys have ever run a HPX 15 with a 50Hp motor. ( I know the boat is rated for 40 HP).

Roger the weight sensitivity. The new Yamaha F-50's (and F60's) only weigh about 25 pounds more than the F-40. For the boost in horsepower, I'd be willing to drop that much weight myself.

I have never seen one. My 40 pushes the boat fine,but obviously not a rocket.  Weight is the deal with these boats. I usually fish sole so it goes pretty good with a 40.

I love this 15 HPX but I've been spoiled by riding on 17 HPXV's with 90- 2 Strokes. I routinely run 20 miles or so each way to fish and on calm days I could save nearly a half hour each way with a faster boat.

Will a 17HPX with a 90 do 55mph?  I can run 30mph WOT with the little 40hp.  Do you feel comfortable at that speed going over flats?  I guess I'm  chicken. LOL

No, I think an 17 HPX with a 90 will do about 47 wide open (HPX 17 owners correct me if I'm wrong). But even at 40, I could run 20 miles in 1/2 hour. Since I don't like running engines wide open, the cruise speed of my 15HPX is in the low to mid 20's so it takes me nearly an hour to run 20 miles.

I have a 2005 HPX 15 and about a year ago I came across a 2-stroke 50 Yamaha, sold my F40 and replaced it with the 50TLR. In my opinion that is the motor this boat should have been powered with from the factory. lost some weight (189lb vs 233lb), more torque, gained about 8-9 mph WOT and fuel burn is about the same if not slightly better. If you can find a well cared for 50TLR I would not hesitate to throw one on your boat. I was getting very close to buying a Key West/Key Largo, swapping my F40 for the 50TLR and then selling the Key West just get the motor.
