I have heard two different theories on which gas to run in older outboard engines. My local OMC mechanic recommends using a mid-grade fuel in my 1974 outboard. However, I read numerous times on this forum to use 87 octane fuel.<br />Does this really make a difference? If so, why?<br />Thanks.
I recently bought a OMC tachometer on ebay that I thought would work for my boat, however I am uncertain now. My motor is a 1974 Johnson 85hp. The new tach says 5 pulse on the front. There are several part numbers on the box that has been lined out. The number on the back of the tach is...

I have a question about an older Johnson boat. My brother-in-law has an older boat built by Johnson. It is an inboard/outboard boat with a 350 chevy. Overall the boat is in great shape, but does need a little work. I believe these boats are rare, and I was wandering what one would be worth...

Here is the situation.<br />1974 Johnson, 85hp. I am replacing the reeds and going with Boyensen reeds. I have talked to people on here as well as a Boyensen reed tech. person on the phone. I am unsure what size jets I will need since I have replaced the stock carbs a while back. The carbs I...
I am sure this topic has been discussed on here before, but I am new to this forum so I am going to bring it up again and maybe somebody can give me some insite.<br /><br />After a closer inspection, I believe I have finally found the cause of my idle problem. It turns out the reeds were not...
I have a 1974, 85 hp Johnson outboard that I cant seen to get it to idle. It will run a few seconds and die, sometimes longer. It sputters a little bit of smoke and then dies.<br />It also will cut out occasionally at higher rpms out of the water, but not to noticeable. It runs great on the...
