[What is the fuel consumption of a 1988 Evinrude 175-HP outboard?]
[How reliable is a 1988 Evinrude 175-HP outboard?]
[How powerful is a 1988 Evinrude 175-HP outboard?]
Has anyone ran [a 1988 Evinrude 175-HP outboard]?
Thanks
Robert

A 1988 Evinrude 175-HP motor will have a Brake Specific Fuel Consumption of around 0.55-lbs/HP/hour. You can use this data to predict its fuel consumption. See:
Brake Specific Fuel Consumption
http://continuouswave.com/ubb/Forum4/HTML/004149.html
I do not have any actual data, but my impression is that a 1988 Evinrude 175-HP motor was of normal reliability when new for a two-stroke outboard using carburetors. The reliability of a 1988 Evinrude 175-HP motor today is more dependent on the condition of the particular motor than on any general trend associated with that type of motor. When a motor is 19-years old and is still operating normally, this achievement itself is evidence of good reliability.
In 1988 outboard motors were generally rated for horsepower using the ICOMIA 28-83 standard. If you do not have a copy of that document I have reproduced it for your convenience, and you may read it online at

At cruise(3500-4000rpms) she should burn about 8-10gph. At WOT about 16-18. Any engne running good at 19 years old could run for a minute or a decade. Engine is worth about $1500 so compute that into boat cost.

Thanks
For the help guys.This website has been so helpful to a ranch hand who happens to be hooked on Boston Whaler boats. I was working for the Hollister Ranch along the coast of Northern California when I was a kid. On our days off we had a little boat we would fish beyond the breakers in. There were some islands out there
that we longed to get to because we heard the fishing was great. We tried a few times to get to them but the seas got too big for our little boat. We would see the Boston Whalers go flying by us and never even slow up. From those days on I thought to myself I would someday get myself one of those.
Robert
p.s. the 175 has about 250 hours on it and sounds real healthy.

Ignore the hours, 18 years old is 18 years old. Get a compression test by a mechanic, check the lower unit oil, and figure on putting a new impeller on any used motor you buy

I have obtained the prop that was on the 175 Evinrude. Would anyone be able to tell me the pitch? The brand of tahe prop is Michigan. The only numbers/letters on it are P J 2 0 2 C U P
Thanks for the help,
Robert
I have not ran the motor yet, I'm just curious about the pitch of this prop.
Tom W Clark posted 01-15-2007 10:28 AM ET (US)
Michigan 15" x 17" Aluminum three blade.

Thanks, Tom for the information. What are your thoughts on the RPM of an 88 Outrage 18? From what I've read, I would think the RPM of the Evinrude 175 would be too high.
Most of our boating is done from sea level to 2,000 feet and we do a lot of waterskiing. This may be a good prop for that. Your thoughts?
Robert

Robert I'm glad to see you settled in on an outrage on your coast. Good luck and enjoy!

A good running Evenrude 175 2 cycle outboard is very powerful. It is like a loaded gun sitting on the transom. Slamming the throttle forward provides explosive response. With a 17 inch pitch propeller, you ought to be able to jerk water skiers right out of their wet suits, or pull off their arms.
Tom W Clark posted 01-16-2007 02:40 PM ET (US)
The 15" pitch pro would be fine for water skiing at altitude. You would probably also want a 19" or a 21" for sea level operation.
Tom W Clark posted 01-16-2007 02:48 PM ET (US)
I meant o say the 15" x 17" prop would be fine for water skiing at altitude.
A 175 HP motor will produce only 165 HP at 2000 feet of elevation.
RobertRibley posted 03-14-2007 11:56 AM ET (US)
I ran the 175 with the 15x17 Wot was 45 mph at 55 rpm .
The outrage jump out of the water when i put the throttle
down. The power was explosive . ? if I was going with SS
What would be a good prop 3 or 4 blade 19 or 21 ?
The lake i ran her was maybe 2500 ft to 3000 elv.
Thanks.

Robert- You have plenty of motor for an 18 Outrage. You should be able to pop a 200 lb single skiier out of a water start, and still have reserve power @ 2500' alt. with the 19" SST wheel.
The 21" SST will leave you too puny on the holeshot with the same skiier, but should work OK for skiiers less than 160 lbs. Good sea level prop.
At sea level, you probably have enough grunt to spin a 23" with a light load in the boat for speed runs.
Best stainless prop for everyday is probably a 14.50 X 17 Stiletto (which gives bow lift, and acts like a 19"), or a 14.50 X 19 SST. They will both run well at either altitude, or sea level. Tom Clark can advise you well on props, and sell you one too. He has owned a like combo. V6/18' Outrage.
All of these should be 3 blade props.

RobertRibley posted 06-01-2007 10:24 AM ET (US)
Tom -
I finally got a day off and took the Outrage out for a test drive with the new prop - the Stiletto 14 1/4 x 15R 3 blade. My intent was to do some fishing first. I warmed the motor up, full tank of gas, kicker motor mounted on the transom, 100 lbs weight, one person in the boat with fishing gear, etc., two thousand foot elevation lake. I pushed the throttle all the way open and the hole shot was explosive - it seemed like the whole boat jumped out of the water. It seemed like in seconds the engine was at 5800 RPM and the GPS hand held read 49 mph. I did not leave it there very long but it felt like it may rise to 6000 RPM. I did this four times up wind, down wind, and every time was the same. It seems like it would pull the arms out of the Incredible Hulk if he was skiing behind it. I think this will be an excellent prop for water skiing and I can't wait to pull up a couple of skiiers with it at once.
Thanks for the help,
Robert

Robert,
I am glad the Stiletto propeller is working out well for you. It sounds as if that was the peffect prop for your needs (high altitude, water skiing, etc.)
