Can anyone be of help? I want to repower my 19' Revenge. Would I be happy with the minimum 65 hp or should I step up to a 75 hp?

I personally think that you will be disapointed with the 65 on a 19. What do you have on it now and what is the max rating for it? By the way, what year is it?

How do you plan to use the boat, and what are your goals... performance, fuel economy, etc.

I would love great fuel economy. I want it to be able to plain out 2 or 3 people and equipment and not drag.it will be used on lake superior most of the time.

maple,
I can't help you any with the size. A 75 or even a 90 just seems too small to me for that boat. Whatever size you decide to get, I can certainly recommend any of the new injected 2 stroke engines. They are quiet, smooth, easy to start, and very fuel efficient.

The 19 Revenge is a pretty heavy hull. I have a 1973 outrage with the cap off that still weighs over 1300lbs. I would never consider even a 75hp on that boat -- I believe it would plain out but your engine would be working hard all the time. If I were looking to stay small I would start with a 90 minimum and really look at the 115. I am converting mine to a low-pro which has no upper cap and I am going minimum rigging. My plan is still to put a 150hp on her and run at about 65% of WOT -- it should just sip fuel and I will have it if I really need it.

The maximum horsepower for the early 19' Revenge model was 170 HP (later increased to 175 HP when the first V-6 outboards appeared).

Personally, I would not put less than 115 HP on this model.

I thought they had the max at 175 on these boats. Hard for me to tell because I do not have the factory capacity plate on mine. These are very efficient hulls and I have seen one run with a single 70hp. I would not recommend that to anyone as a primary source of power. This boat had twins and he could get up on one if he had to. 155 is a great engine for that boat if you have no water in the hull -- it all comes down to her weight. Go to some certified scales and see how much you need to push than make the decision.

Thanks for all the advice guys. the people i bought it from had a 74 115hp. I want something more reliable.

A new 115 would be much more reliable. Why are you looking to power down so much? Are going to twins? Twin 75hp would be very reliable.

Don't forget about the Etec 130, might be a nice alternative for both power and economy...

I just wonder why they would put 65hp min when it would'nt be adequate. This is my first whaler and know little about their preformance. I think boat manufacturers need to come up with a better system for rating hp to boat.

Well adequate is all dependent on what you'll use the boat for. 65 HP is the min that will get that hull on plane. And if it were just you running around a calm lake very lightly loaded all the time, and you didn't mind a long acceleration time to plane, low top speed, etc, you may be happy with the 65. But from what you say above, it sounds like you'll need more power.

mapleleaf - trust all of us here when we say you would not be happy with the minimum hp selection. I am by no means a power /speed type of guy. It was real hard for me to say I wanted a 150 on my 19 footer -- I would much rather have the 115 V4 for fuel economy but think my boat is going to be to heavy to pull it off. If you are going to invest the dollars in a new motor better be sure you are getting what you want or need.

Mapleleaf - Do you have any interest in either this '74 Johnson or '83 Johnson, or both? They have recently been removed from my similar 1975 19 Outrage, same hull as yours, stored indoors at my dealer. The engines are practically brand new and in perfect running condition. The 1974 might be particularly nice on your '74 Whaler if you're not looking for a lot of top end speed. My 19 was originally rigged with this engine as a single. Boston Whaler's 1977 catalog indicates that a 19 Revenge will do 25 MPH with a single 65/70HP engine, and 36 MPH with twin 65's.
