I'm looking at a boat with a 88 Johnson outboard, guys said it ran when he got it but cut some wires under the consoul and has not started since.

Hello, welcome to JustAnswer. because of the range of possible issues, this may take more than one post. Please, don't hesitate to reply.

 

The compression is the most critical indicator of the motor's condition. Without being able to start the motor, you are taking a risk. I tell most folks that if you cannot test the motor in the water, be prepared to walk away for the slightest reason. Even hearing the motor run on the trailer only tells you that might work in the water. You are looking at a boat with a motor that doesn't run. If it is just a matter of cut wires, you need to ask why they were not simply connected back together so the motor runs. Failing to do a simple repair when selling a boat is a BIG red flag. And cut wires is about as simple as it gets. Just put the matching colored wires back together.

As for finding you the year, I will need to have the motors model number to do that for you. It can be found on a tag on the mounting bracket that holds the motor to the boat.

No numbers found on the mounting bracket. But the boat is a 1988. Guy thought the motor was bought with the boat. He is the second owner and bought it form the first owner whom he knew. Model is a SPL 88. I didn't see a oil injection tank, so I guess the oil need to be mixed with the gas. Batteries are dead, so they will need to be charged or jumped proir to taking a compression check. I could turn the flywheel and feel some compression.

The 88 models were made between 1987-1990. Without the model number I cannot narrow it down any closer than that.

But being that the boat is an '89 the previous owner assumption is almost certainly the correct one.

If you look at the power head, the model number should the stamped on one of the freeze plugs. I think it is on the top of the motor, but don't hesitate to look the motor over if you cannot find it there.
