90 Horse cruising speed???

[amptheripper21]

I just picked up my new ( to me ) 22 cruiser yesterday and couldnt be happier. The boat has a two stroke 90 Johnson on it and i was just wondering if anyone has a similar setup that could give me an idea of what type of cruising/ top speed they are getting. I wont be able to get it out for a little while but i'm trying to educate myself about them as much as possible. Thanks to anyone who could help.

I had the exact same set up. I could get up around 26 mph but these boats are really designed to cruise around 18 or so. About 4000 rpm if I remember right. I ended up getting a new 4 stroke engine for reliability reasons up here in alaska. Better gas mileage and quieter too. But if your Johnson is in good shape there is no reason why it wouldn't give you good service.

amptheripper21 – can’t answer your question but would like to welcome you aboard. It seems like we are starting to get a few C-Dory owners in this area. Glad to have you aboard and look forward to crossing wakes someday.

I have a 70 HP Yamaha 2 stroke which still seems to run like new. While I'm coveting a 90 4 stroke the performance of the 70 doesn't justify it. I seem to get great mileage in regularly choppy seas. And, the engine will push the boat as fast as my dental fillings will allow -- with 22-24 mph being about the fastest (on the one glassy day I've seen here in Channel Islands I was able to maintain 25 mph for extended periods).

But, as Lee pointed out, the boat really prefers (and is much more comfortable) at 16-18 mph.

Of course, it would be great to have a quiet engine, smooth at idle, and smokefree... so the 4 stroke is definitely in my future.

I had a 1987 90 hp 2-stroke Evinrude (OMC, same as the Johnson) on my 22 Cruiser when I bought it.

When I first got it and kept it light, would run from 28-31 mph in flat water and cool air at sea level.

A year or two later, moderately heavily weighted down due to my obsessive-compulsive "Be Prepared for Anything Syndrome", the max out came down to about 26-27 mph

Actually, that's not a lot of loss for all the stuff added aboard.

The OMC 90 2-stroke is as very reliable and strong engine, even if it is a bit of a smoker.

Do you have a VRO (Variable Ratio Oiling) model with a separate oil tank and automatic mixing of oil and gas?

I used a 3-blade aluminum prop with a 15 inch pitch with my boat. It's extremely important to keep the prop and skeg clean and smooth for maximum speed. Ditto for the hull bottom. Dings, rough edges, moss, and barnacles ='s a case of the SLOWS! A lightly dinged up prop alone can subtract 2-4 mph from your top end!

Enjoy your new boat!

im kinda in the same boat, just got a 22 angler and im putting my 1997 90 horse johnson on it and im wondering what kind of fuel economy ill get so i can figure out how much fuel to carry, im thinking 35-40 gallons, anyone with a similar set up would shed some light on my situation too, good luck to you...

SWAMI SEZ-

The CD-22 with a 90 hp 2 cycle engine should be able to give you about 4 mpg at cruising speed, depending on a lot of variable factors.

You can get maybe twice that at displacement speeds, ~ 5-6 mph or less.

Max mpg over a mixed range of usual cruising at displacement and planing speeds would be about 4.5 mpg overall, and the minimum overall for the same range about 3.5 or a little less under adverse conditions.

A four stroke engine will give you up to one more mpg average, especially with Electronic Fuel Injection.

But as they always say YMYV (YOUR MILEAGE MAY VARY!)
