Just picked up a 2002 Nissan NS9.8 B 2 Stroke outboard on a 10 foot rib inflatable. The combo runs great, but I am having trouble sorting out the idle RPM. The engine runs great, pushing the boat 16 MPH.
It is a 2 cylinder 2 stroke and I am trying to measure the RPM using a Oppama PET 1100R...
I have a stock OMC 13.25 x 15 - 3 blade aluminum prop on my 70 hp 2 stroke Johnson motor. With 2 people in the boat I am hitting 6200 RPM and around 31 MPH. Max RPM should be around 5500 RPM for this motor. Would a 4 blade Solas Amita in 12.75 x 17" pitch give even better low and mid range...
I have had this engine for around 8 years and just recently I have noticed that is smokes at idle. Starts right up, runs strong up to redline, but when bringing back down to idle is blows smoke. It has never done this before, generally at idle there hasn't been any smoke at all.
Does this...
My engine is running great, but the buzzer is non-functional. When I ground out the temp switch wires (either the tan/blue or the white/black) on either the engine side or control side and turn the key to run the buzzer does not buzz. I took the cover off of the controls and wired the buzzer...
I recently rebuilt my 1995 70hp motor since one of the pistons was burnt. I am in the initial break-in period and the engine will no longer idle. I ran the motor today for 2 hours with double oil (VRO plus 50:1) in the tank, and replaced the spark plugs once since the engine would not start...
I just started pressure washer sandblasting the multiple layers of bottom paint off of my 1969 Boston Whaler. What I have found has been less than satisfying. I was hoping to wetsand and buff the bottom, but it appears the gelcoat is too far gone for that. I guess the idea now is to fill and...
I don't think my 1995 70 hp Johnson has quickstart, is that correct? Is there a matrix anywhere that states what years/models have it? Based on a search, if you have an orange wire coming from the stator you have quick start, is that correct? Also, grounding the temp sensor will disable quick...
I started rebuilding my motor tonight and just realized that the rebuild kit from Powerheadkit.com only came with a lower main bearing. My current lower main bearing feels really good as do the two middle main bearings. The upper bearing was completely dry, but very smooth. I actually can't...
I read everywhere that the carb float should be parallel when upside down and in the manual mentions around 1" of droop when rightside up. If these settings are off, how do you adjust? Bend the bracket with pliers? That is the only thing that is not clear in the super secret file.

Putting my 1995 70 Johnson back together and didn't capture in any picture where the ground wire is connected to that goes from the exhaust housing to the tilt bracket to somewhere? up in the engine bay.

I am waiting for my block to come back from boring and honing so I can start rebuilding it. The previous owner burnt a hole in the center piston. I was warned to figure out why the motor burnt the hole since it will just happen again so I am trying to figure out how to troubleshoot it. What...
I need a new bunk trailer for my whaler that weighs around 1500 lbs fully loaded. On the low end is the 5-starr Loadrite welded model 5S-17220090V for $1399. On the high-end is the Tidewater for $1645.
Any pros and cons to these trailers? Is the 5-starr loadrite a decent trailer, anyone have...
I have a 1995 70 hp Johnson with electric trim and tilt. I disconnected the controls so I cannot tilt the motor. I unscrewed the manual release on the starboard side of the engine and the motor tilted all the way down. When I try to lift it up I am met with a bunch of resistance.
What could...
Just bought a boat today that has a Johnson 1995 70hp 3 cylinder engine. The engine starts right up but runs really rough. I had my compression tester in the car, but decided to leave it and low-ball the seller. Tonight I did the compression test and two of the cylinders are 100 psi and the...
