Hello! I have a question about timing on this Johnson. I dont know that it is timed correctly and I just want to check it. Unfortunately I dont have a large enough test tank. I seen a post by Joe Reeves about timing without a tank or wheel simply by subtracting 4 Degrees on this post...
Hi Guys. I recently bought a used 1971 Johnson 100hp and found out that the carbs on the motor are not the stock carbs they are from a 125 hp motor. They do not have the slow speed adjustable needles that this motors carbs are originally equipped with and so it runs a little rich on the bottom...

Hello Again and thanks for all your help on that 1971 Evinrude 60HP I had which didnt pan out for me but I am going to purchase a new motor today. From what the seller tells me it is a 1971 Johnson 100HP V4. Supposedly it has sat for 20 Years in a warehouse before he got this motor. It had...
Yup I wanted to take the boat out this weekend but there was that knock again I couldnt help but tear the motor down and find that Piston one with the low compression was melted pretty good. So I think I may rebuild. On the underside of the pistons there is the M logo which I think is Mallory...
Ok I have an issue I havent encountered up until last night. I was assembling the new water pump housing and getting it ready to install on the LU. I was using a tap to clean out the threads as I usually do just for good practice and on the last hole the tap broke off inside.... Im not able to...
Im not sure where to start with this as I haven't been able to put the boat in the water and test it to see if it knocks all the time or not or just in nuetral or whatever. I dont think this knock is normal. Here is a video what do you guys think? Should I tear the head off and check the...

Ok I have searched around but i cant find any info on my problem. The Lock Nut that attaches the steering cable to the tube at the rear of the boat will not thread back on to the tube.... I dont see any thread and it doesnt look as that there ever was any.... when I turn the wheel to the left...
