I have a 1985 nitro mx17 fish/ski boat.
It has a 1985 2 stroke 115 hp Johnson outboard motor.
Question 1: What is the rpm operating range at WOT?
Question 2: How many rpms should there be right before break over on the hole shot?
Thanks!
The hole into the livewell measures 1 inch in diameter. I looked everywhere online and can't find a tube that is 1 inch. Found a tube that was 7/8 and another that was 1 1/8. It was then when I began to second guess the size of tube I need. Anybody have any ideas? By the way, the tube...
115 hp 1985 Johnson outboard motor
The motor pushes the boat great! The boat idles good. Motor will occasionally die at idle but not often. Here is the problem: Each time I start the motor I have to throttle up before each start. It doesn't matter if it just went on a 10 min run or if it's been...

I have a 1985 2 stroke Johnson 115 hp outboard. It runs 4500 rpms at WOT trimmed all the way up. With an added weight of around 300 lbs it will run 5000rpms with the trim in the same position. Do you think I am over-propped and working my motor too hard?
First, I must say thank you for everyone who took the time to help resolve a couple of boat issues I had within the last couple of weeks. It seems like things just keep coming up here recently. Oh, the joys of boat ownership! I would like to solve the issue with my trim gauge not working...
I have a regular bilge pump. (Not automatic) I was on the lake today and did not even use the toggle switch that controls the bilge and a flasher. Towards the end of the trip, the bilge came on and I had to disconnect the inline fuse to get it to shut off. All I normally have to do is...
Flywheel nut torque spec for a 1985 Johnson 2 stroke v4 outboard with a 115 hp motor Please let me know if you know what the book says the ft-lbs torque is for this motor. I have been all over the internet and flipping through an owner's manual without anything conclusive! The only thing I...
