Question on 1998 150 hp evinrude FICHT

[Dr W]

I am buying a boat with an Evinrude ocean 150 FICTH  outboard that runs well but misfires a bit at mid range

Does anyone have any idea of where I should look to correct this issue ?

I have been told that this motor class has had some issues ?  Some of them run well and others never do.

Love to here your thoughts,.

I don't think the 150's were problematic, but you are buying a 21 y/o outboard. It's a crap shoot whether it's a cheap fix or ready to fail completely.

Lots of possible causes of a mid range misfire in an outboard.  Might want to proceed carefully in repair to a 1998 Evinrude FICHT as Evinrude had issues in that time frame which lead to bankruptcy in 2000.  If some fuel filters or spark plugs won’t fix the miss, it probably isn’t worth putting much into repairs on this age outboard.  Probably should talk with an old Evinrude dealer or marine repair business.  BRP did a redesign on the Evinrude after they assumed ownership so the later engines are different from the old OMC product.

I had a 2001150 that ran rough for a year, have you checked the exhaust sensor? I chased this around all summer until I changed a $60 part then everything was fine.

I'm currently running a 1989 Evinrude 150 on my Crestliner. It runs great after I paid a local marina to tune it up for me.

 

It ran rough at slow speed when I bought the boat, and ran good at higher speeds. I took a chance and I'm glad I did. The motor had its VRO disabled and removed by a previous owner, and I left it that way. Compression was good on all 6 cylinders.

 

The shop replaced the water pump/impeller, diagnosed and fixed a low fuel pressure issue and replaced a main gasket at or near the bottom of the power head. They did some other work on the boat and motor and it runs like it has another 10 years left in it, maybe longer. It was well worth the $900 it cost for the repair work.

 

I know it's not a Ficht motor, but there are some good older motors that still run great with some initial investment.

For what's its worth I have a 1997 115 Johnson and  as a weekend fisherman the motor at the end of last season has 432 hours on it since when I bought it new, my trolling motor is the 3rd one in the same time frame so maybe it just needs a good once over.

I know you not that close to Buffalo but Brobil marine is a top guy for your motor

I had the same problem! About 1800 to 2100 she had noticeable miss! Drove me mad! Turned out to be the emm! I found an 97 evinrude 150 picked up for the lower unit! Decided to swap ecu and see if it helped! And it was an instant fix! I picked up a good 350 rpms and 7mph to boot! Anyone who claims the emm needs to be programed to the injectors is mistaken! However the injectors shouldnt be changed from one side to the other side! I hope this helps someone somewhere!

my mechanic found a guy who rebuilds and reprograms the computers and this fixes most issues along with a new fuil pump. but i will try this first. being cheeper,

Run away from that thing! But if you need one for parts let me know...
