Just wanted some info on re-powering my 80 FF it had a 175 Evinrude but previous owner took it off because he blew it. would a 150 be under powering it. thanks for any input
-
A newer 150 would be perfect, as much power as a old 175

I'm guessin' it's a 22 FF.
If so max hp is 245 like the CCP of that era. In 84 mine came with a 185. I re-powered with a 200 and that's pretty much the hp of choice for those size hulls. Again, if it's a 22, then your listed weight is 2200lbs (like the CCP) and rated at 245 hp. I'm thinking a 40hp would move it around but something along the lines of a newer 175 or and older 200 is the ticket.
What is the year and make of the 150?
Good luck.

Thanks Matt & Bob for the replys. Its a 1980 22' FF in real good shape I found a couple of 1989 150's but i dont want to be under powered. I started out on here with a 73 222 CC with a 1985 evinrude 115 and she ran great so i want to be just as happy with this one
-
Oh and they were Evinrude's and johnson's thats what was on it
-
Mine is a 78 22FF with the modified V. I have a 96 Yamaha 200 SW series and it is a great match. However, I'm sure a 150 would push it fine. You'd probably get a top end of about 36mph. If you do a search, someone on here repowered with a 150 if I recall. Those new 200 inline 4 cylinders from Yamaha would be sweet on this boat.
-
If it's a deep vee I would try to go with a 200.
I run about 30 mph at 4000 rpms. Get a top end of close to 42 mph.
Had a 225 on my 79 222 FF before the 200 I got now.
Numbers where about the same.

I found a 1994 evinrude 200 totally rebuilt its a looper engine whatever that is. Is this a good motor?
-
A "looper" is a 2-cycle engine. It's just slang.
-
A looper is a loop charged two stroke OMC motor. It has to do with how the intake charge is drawn into the cylinder. Not all two stroke OMC are looped charged some of them are cross flow induction. Generally the crossflow motors idle better and run better at low rpms. Loopers don't idle as good but usually have more power at high rpms.

Thank you guys for all your help. I don't know that much about outboards I'm normally an inboard guy. Is there a difference between an ocean pro and an ocean runner and just a 94 200 HP evinrude
-
Hat tip to Wingtime... I didn't know that.

OPs are Evinrude's nomenclature while ORs was Johnson's for their respective saltwater series engines. Think more stainless parts.

Thank you capt bob for the info. Everybody on here is a real help and not to mention all the rebuilds are amazing thanks again, Ted

A looper is a loop charged two stroke OMC motor. It has to do with how the intake charge is drawn into the cylinder. Not all two stroke OMC are looped charged some of them are cross flow induction.
To further expand, there is a difference in the shape of the piston crown. Typical 2 stroke motor has intake and exhaust ports machined into the lower part of the cylinder walls. As the piston travels up and down the skirt covers and uncovers the ports to allow for the exhaust purge/aircharge to happen. The result is that at one point in the cycle (piston traveling through bottom center) both ports are open. The air charge that has built up pressure in the crank case due to the piston displacing the volume from the roughly top center intake volume to bottom center rushes into the cylinder under pressure while the expended exhaust gas is still going out the exhaust port. With a typical flat top 2 stroke piston shape a slug of the air fuel charge mix goes right out the exhaust port and some of the exhaust gas is trapped in the top of the cylinder... Not the most efficient mix..
To keep our hard earned and payed for fuel in the cylinder and to get a better exhaust purge during this evolution, some old boy way smarter then me decided to put a funky ramp shape on the piston head to keep the air/fuel charge from blasting straight across the piston and out the exhaust port. The ports were modified in some cases too with an appropriate angle to further direct the airflow in the direction it needs to go.. Damn genius I think.. The charge would now be directed up to the top of the cylinder to displace the rest of the exhaust gases and keep the fuel mix where it was supposed to be, next to the plug waiting to go boom... Hence the loop charged motor was born.. :cheers:
-
Just to add to that history, looping the charge (via port shaping) also allowed the deflector dome Dave mentioned on the top of the piston, to be greatly reduced in size and reshaped. This in turn reduced the piston's weight and uneven heating. Coupled with a well designed expansion chamber, the tendency to burn holes in piston tops was reduced also. While outboards are water cooled most two stroked motorcycles (in my memory) were not and this was a great help in even heat distribution.
Interesting stuff and flashback inducing, to an earlier life.
Thanks Dave. :thumright:

I was keeping it simple but yes they are correct. A cross flow is just that... the intake port and exhaust port are directly accross from each other and the piston top is basically flat so the intake charge can flow directly across the cylinder hence the name. In a loop charged OMC engine I think they have three intake ports and the the intake flow is directed upwards into the cylinder by the shape of the port and the strange ramp shape on top of the piston. When the intake charge flow nears the top of the cylinder it then loops backwards down towards the center or the combustion chamber.
Here is a great link with pictures that explains it even better: http://www.maxrules.com/fixtheory2.html
The difference between an Ocean Runner and a Ocean Pro is basically just the sticker. One is Johnson and the other is Evinrude. Both of them have stainless parts instead of regular steel used in their fresh water brethren to cope with the saltwater environment.

Gotta love this!! :mrgreen: :cheers: :thumright: :thumleft:
My pleasure CB, and that is a really good link Bruce!! :salut: :salut:

I have a 140hp 2-stroke on my 222FFV.
It works, but I would prefer a bump up to a 175 or 200hp.
Issue is weight on the back and dryness of hull.
If money were not an issue I would do a 225 Etec.
Else a DF175 for new.
Old motor....an OX66 in 200 or 225.

Thanks again for all the info you are all very helpful. So I went with the 200 evinrude totally rebuilt rigged installed and a 6 month warranty $4000 can't wait to get out for some striped bass. I posted about the FF forum that was on here but I don't see it anymore does it still exist I like all the pics of other boats. Good day to all, Ted
