Author Topic:   70hp and 90 hp Johnsons

I am getting some electrical work done on my 1977 Montauk. It currently has a 1990 60 hp Johnson. The fella who does the work has heard of a local company that has bid on the complete inventory of 2000 and 2001 OMC Johnson engines. If this happens I will buy one because: 1) The price and 2) I'm a Johnson guy and my boat is rigged for one. My question is this: Which one? When I bought my boat it had a 115hp Johnson that went about 45+ mph. I thought it was too fast. Then I bought the 3 cylinder 60 which is OK but a tad slow. I like the weight of the 70hp (250) and the power of the 90hp. I'm calling out to all that have experience with both engines to tell your tale. (Good, bad, and ugly).

I just went from a 115 to a 90 on my '85 Montauk. Like you I thought the 115 was pretty fast and some people might say too fast. I kindof like it. The 90 is about 4-5 mph slower but I bought it cause it was a good deal. If you don't care about gas mileage, insurance isn't a problem, and the price is right I'd go with the 115.

I am replacing the Johnson 70 (30 years old) on my boat with a Johnson 90. I like to cruise at 30 and at that speed, the 70 is running wide open. With the 90, at 30 mph, the engine is hardly working. My point is that a motor that isn't working as hard will last longer.

And, the 90 will do a much better job of pulling up 2 water skiers.

In another thread in this forum, somebody (maybe jimh) made a good point. He said he never met anyone who wished they had put less horsepower on their boat but he had met plenty of people who wished they had bought a larger engine.

ron I agree with you but then you agian....your 70 is 30 years old so how long do you expect the 90 to last.....60 years:)

Double the life would be nice for what these dag-blasted things cost but, I would settle for 30. 30 years from now, I want to buy the latest 100 hp 4 stroke that weighs 100 pounds and runs on a hydrogen fuel cell. I wonder what my whaler would be worth 30 years from now when its 63 years old?

I had a 60 hp 3cyl (1998) on my Montauk at first. I upgraded to a 2001 Ocean Pro 90 hp.

Best move I could make. I normally now cruise at a lower rpm, and still move along at a decent clip. I also have the ability to haul *ss if I have to.

Oh yeah, the 60 went back onto the 1977 Sport 15

Does your friend have any 150 hp motors or even a 130?

There is some risk in buying a 2000 or 2001 OMC engine, if one believes Bombardier's most recent comments about these engines. See the General section for direct quotes from Bombardier about the quality of these products.

As most know, during the last 3 years of their existance, they were outsourcing most of the components for their engines, a major mistake that broke their back. Many of these parts were of poor quality and lacked proper tolerances, according to Bombardier themselves, and they decided to junk millions of dollars worth of these parts in inventory, as unuseable. Just remember, these are the parts that were used in the 1999-2001 engines before they closed their doors. Right before they collapsed, they were rushing as many engines through production as they could, having enticed Dealers to buy these though deceptive marketing. So buyer beware if you get one of these.

In spite of the hundreds on this site who are very happy with 50-70HP engines on their Montauks, I am still convinced that a 90 is the best all around long term choice. You don't run you auto around in second gear, so why do it with your Whaler?

I got my '82 Montauk with '82 90 Evinrude in '88 and ran it for 8 years without a problem. Faster than a lot of boats, slower than some. That's OK. The Montauk and an OMC 90 is a great combo. I could count on 4 mpg.

my 62 nauset has a 99 johnson 90, and I love it. I get better than 3 gal/hr (2.3 gal/hr from my last trip). Tops out about 44 mph, and is underpropped, probably capable of 46 or so with another 2 inches of pitch. Good match for the 16/17 hulls.

Thanks all! I'm gonna go for the 90hp if the price is right. I'll also see about other HP engines.

As for the quote about engine power that was attributed to me, no, I am not the originator. I think LHG very likely said that some time ago.

Another comment about engines and horsepower that I heard recently and like:
"If you need a little more horsepower once in a while, it is a lot easier to just push the throttle farther open than it is to put a whole new engine on the transom." (Don't have a good citation for that one, though.)

Nothing but glowing reviews for new 60 degree 90hp motors. Does anyone have any problems from what lhg above is stating?

If it is a carburated! Stay away from the pre 2000 Ficht if possible but if the engine has a good track record, then it is probably a "good one" and considerations should be made. Would I buy a new Ficht with NO warranty? Not unless it was given to me real cheap. Would I take one with warranty...yes.

I'm talking 90hp two stoke, carbed Johnson. No DFI or 4stroke for me yet. These will be new, in box, with full warranty.

I know, I posted that in the wrong place. Disregard and go up one post where I say Carb is cool. Great engine...go for it. keep us posted if they have more than one...might have some buyers here. I need a 25HP longshaft:)

Those who have the Johnson 60 degree, carbed 90hp on their 17 footers. A question: What prop size would you suggest?
triblet posted 02-27-2002 12:49 AM ET (US)     Profile for triblet  Send Email to triblet     
I have an Evinrude 60 degree 90 HP on my
Montauk (same engine). It has a 14" diameter
17" pitch prop. Works well. Pulls up big
water skiers on a single (my buddy Paul is
probably 240), top speed about 41 MPH at
5300 RPM, just me, 3 gal gas.

As noted above, my Nauset has a 99 model Johnson 90. That's the 60 degree carbed engine you're looking at, and I love it. I'm running a OMC Viper prop, 13 3/8 x 17. I'm underpropped, and can turn 58-5900 RPM if I'm not careful (redline at 5500). Still hit 44 on the GPS, while running upwind and against the tide. On the somewhat heavier Montauks, this might be the ideal prop.
