1975 85hp Evinrude Two weeks ago the boat ran great when last we had it out. Last weekend drove 90 miles for a lake weekend and it would not fire up. Checking it out today I find that I am getting spark on cylinders 2 and 4, but no spark whatsoever on 1 and 3. I checked, cleaned and...
When I got my boat and trailer I noticed the right side running light was not working. Since then the right taillight seal leaked and blew the bulb and corroded up. While it was out the sidelight started working fine. I cleaned up the taillight and fixed the seal and bulb and it works fine...
I need a new power pack on the '75 85 HP Evinrude and went to the BRP catalog to get the part number...0581311. When I get on iboats to look for it and enter my engine info it gives me a long list of powerpacks but none of them list this part number as an OMC replacement. Can I use the ones...
Several days ago I posted about no spark issues in a rectifier wires post and at the end had gotten the boat fired up again. Well it quit getting spark again for the last four or five days. Today I went out with a homemade DVA adapter to attempt to run through the CDI troubleshoot. When I...
I have been trying to do a compression test. What I've read says to use a jumper wire or remote switch between the battery positive terminal and the solenoid voltage "in" cable terminal to crank it. Is this correct? I have a remote switch I have been trying to use to do this but when I press...
Does it matter which yellow wire connects to which terminal? 1975 85 HP evinrude. There appeared to be no difference between the 2 yellow wires on the new rectifier. I went by where they came out of the back on the old and new. I've been starting and running the boat for four straight days...
This is the same issue I posted about before but started a new thread since my old one is buried and I've now changed to thinking maybe its a spark issue rather than fuel.
I started the boat up this morning. It started up and ran fine for about ten to fifteen minutes warming up. It then began...
I finally got the motor running on muffs and tinkered with the thottle setting for idle. I ran it the first time for about ten to fifteen minutes. Right off the bat it surged and sputtered around a little then settled in and ran smooth for about ten to fifteen minutes. Then it suddenly...
I finally managed to find a few spring-like days in these weird Christmas-like spring months to get the fuel/starting issue solved I asked about a couple of weeks ago. Turned out to be a combination of a stuck needle valve and the fuel line sucking air from somewhere. Carb cleaning and...
This is my first boat so don't be surprised to see a few moron moves or questions in my discussion. I have a 1975 85 hp Evinrude on a 16' deckboat. I had posted awhile ago about issues shifting to reverse which I did get resolved. The cables were not installed properly and were slipping...
I posted a week ago about a problem I was having getting in reverse. To put it simply when I adjust the linkage it naturally should line up to engage the gears like: R <--- N---> F But I can't get the adjustment to put the boat in reverse until I have already taken forward and neutral out of...
I've been following the forums for a few weeks now (since I bought my first real boat) but this is my first time posting.
I have deck boat with a 1975 85 Evinrude. A family friend completely restored it and he had it out only a few times since, but he insists this worked fine when he did.
I...
