Hello all,
I am trying to figure out a prop to help optimize my boats performance. I am running a 1992 Concept CC 17'6" with a 1.6l (115hp) 1985 OMC seadrive powerhead on a johnson mid and lower. My current numbers are 6000-6200 rpm at 44mph at optimum trim angle (about 3-4 seconds) with a...
Re: Outboard mounting height 1985 Johnson 115 v4
The wire weren't solid core. They were spiral core wires. I replaced them with solid core today. But I ran into another problem.
Update: Okay all, I need some input. I pulled the powerhead and replaced the base gasket. The old one was shot as...

Update: Okay all, I need some input. I pulled the powerhead and replaced the base gasket. The old one was shot as expected.
Unfortunately, When I got the head off, the flat portion of the head nearest to the back, between the head bolts and the...
Hello all,
I am attempting to track down and fix several problems with my outboard. It is a 1985 OMC Seadrive 1.6L Powerhead on a johnson 115 mid and lower. I have a steady drip leak of fuel coming from the part detailed in the attached photo. It drips a fairly large drop about every 2 seconds...
Re: Motor only runs good with cowling off :-(
Here are some pictures detailing the area where I have an exhaust leak. As previously stated, the leak isn't constant, but it definitely is leaking some. The leak is coming from under the square part in the front and from the gasket area of the...

Haffiman, here are the photos you requested.
I will try to figure out what the problem is. I think the motor might not be running perfect or something. When I first get out on the water and run, it...
Re: Outboard mounting height 1985 Johnson 115 v4
Sparkie, Thanks for the reply. When you say I should be set to 6P, does that mean 6 pole or to the 6 setting on the tach. The tach is a faria outboard tach. When I read the manual for the tach, I understood it to tell me that I needed to use the...
Okay guys, I know this sounds a little out there, I unfortunately purchased a used V1500 prop thinking that it was the appropriate prop for my 1985 115 V4 Johnson. It was a marine flea market purchase and the seller was either confused or intentionally misled me. I am trying to go to a 15 pitch...
Hello again, this time I am trying to sort out a fuel venting problem.
I have 18' CC with a below deck fuel tank. When I rebuilt the boat and floor 2 years ago, I installed a recycled alum. gas tank below deck. After cleaning and coating the outside of the tank with coal-tar epoxy, All of the...
Hello,
I Have a 1985 OMC Seadrive 1.6L and and OMC control box from the early 90s. The control box does have the three wire tach hook up coming off it. My question is do I have to buy the wire harness for the tach, or can I just cut the plug off of the end of the wires coming out of the control...
