Ok all, I know I have talked a little bit about this boat but it is almost time to put a new motor on it. First I was going to go 4-stroke, then because of weight I went back to 2-stroke, now I am not sure what I want to buy. Here is what I want to do though and maybe you all can help me out.

I want to be able to pull 1 slalom skier fairly solidly behind this boat. I plan to get a ski pole so I really need a torque motor. So I am really pushing to get as much HP as possible, that knocks out the 75 Evinruki and only leaves me with about 3 engines to consider.......

90 Hp 2-stroke Yamaha
90 Hp 4-stroke Yamaha
90 Hp Johnson Bombardier

Here are some more of my problems/thoughts. According to Yamaha's web site, for 2 equally equipped boats the 4s gets about the same fuel economy as the 2s, and it weighs about 130lbs more + an extra $2k. Also, no dealers in my area will have a 90 Yamaha of any type for about 2 months.

Johnson 90hp has the best warranty, full total coverage for 2 years. The Yam. warranty is only full for the 1st year and partial for the 2nd. Supposedly the Johnson 90 everyone says has the most power of all because of its 60 deg. V-4. Anybody have any long term history with these? I know Masbama loves his, and it is encouraging to me.

Thanks all, sorry about the length.

Look at the Suzuki 90 oil injected. I don't have the weight right off hand, but it gets up and goes. I get great fuel economy and I got a 3 year warranty.

What about the Mercury 115 EFI 4-stroke. You can pull all the slalom skiers you want with it, WOT is 50 mph, and it is smooth an quiet. See

That would be great, but it would be overpowering the boat thus voiding any kind of warranty.

Also, in the event of an accident, no matter the fault. The first thing looked at is if all the boats meet the regulations. Thus, I would be open to loose my captain's license and wide open for liability lawsuit even if someone hit me. That's just how maritime law goes, I have seen it happen before.

Plus, your insurance can also not cover you if you are overpowered.

Ahoy, Tully_Mars.

The 115 EFI 4 stroke Merc would also be too heavy for your 16.

I think you are selling the Suzuki DF70 short on torque, but that is your choice.

I agree that the Johnson 90 is the best value around in a 90, but the Evinrude DFI 90 will be cleaner and quieter.

There may be some substitute for cubic inches when one wants torque, but 70 cu. in compared to 105 is too much difference to ignore. The Yamaha 90, though a fine engine is still only 70 inches, while the Bombardier pair are 105.

Like masbama, in the spring, I repowered with a new Johnson 90 2 stroke. My brother did the same 1 year ago. Although this is no long term history, neither of us has had any trouble whatsoever with the 2001 Johnsons. That Johnson 90 is the largest displacement 2 stroke 90 that you can buy. Like you, I was on the fence between the 4 stroke and 2 stroke motors. I wasn't worried about the weight difference but I simply couldn't come up with the money for the 4 stroke 90. If you buy the Johnson 2 stroke 90, you will be very happy with the motor. It is an extremely "torquey" motor on a 16'7" Whaler. With my boat, at take off, the water skier better have very strong shoulder muscles because when I punch the throttle, the skier is in danger of having his arms ripped off. Ain't that right masbama?

Take a look at the Tohatsu (Nissan) 90 2 stroke and TLDI 2 stroke.

Defintely go with the four cylinder bomb. Johnson or Evinrude if you are pulling adult skiers. The new 60 degree block is a big improvement from the old 90 degree blocks; I have owned both. Good luck!

Well, the people have spoken. It just seems to make sense to put a two stroke 90 on the back-either one. One thing to think about: I went without the VRO because I didn't want the oil tank taking up room. The Yami is intergrated into the engine. That may be a factor with a ski pole. Let us know what you decide!

I love these people that jump in and say you can't overpower a boat.. There are absolutley no laws from the CG about hp. All they do is recommend... I personnaly have insured 4 different whalers with 110's and 115's. Most insurnace companies will insure 10-15% over. Boats/Us has no problem with 115's on whalers..

The only engine for that boat is a 115hp Evinrude Ficht..The boat will get up and fly and cruise on fumes...

All, I might have found a motor.

I have found a 2001 Evinrude 90 Ficht for sale, brand new with 2yr warranty at the price of the Johson Carb model. The nice part is the dealer in about 50 miles from my house in MS. What do you all think? This would be a good motor??

Dunk would know more about the Fichts but I hear they are good engines. I believe that your hull is a bit lighter than the 80's and 90's hull so a 90hp Bomb will make it fly out of the water.
Are you buying it from the same dealer I bought mine from?

Ok all, here is the decision. After talking with a friend of mine in Mobile who used to be an OMC Technical rep in the southeast (now owns a boat dealership) I have gotten a 75 FICHT to go on this boat.

Breath's boats in Bay St. Louis has the 2001 Ficht 90 if anyone is interested (BW dealer too.)

The 75 is the same motor as the 90 just detuned on the computer, and actually low-end torque is supposed to be higher than on the 90. Also, this 75 is a 2002 that I am getting for a really good price with 2 1/2 years of warranty (was a demo motor but still in the crate). Also, I have the option that if it doesn't pull me on a slalom ski like I want I can still get a 90 Johnson!

Good Choice. Let us know when it is ready so we can see it at Sand Island. Sounds like Boat Mart did you right!

That is supposably a great engine....heavy as hell.....but a great engine. Even the OMC Ficht v-4's were very dependable. Only the 200-225's ahd major issues. You will be very happy with your choice, my friend loves her 1999 90hp.
