The 2 steps to start with.-----Compression test.-----Post the values.-----Then a spark check.-----Does spark jump a gap of 7/16" on a test device ?-----How did the motor run for you last season ?-----Is oil injection in service ?----Was it tested for output ?------Or mixing at 50:1 in your tank ?

Thanks for responding, I bought the boat as is it ran on muffs, the guy I bought it from was up front and told me it stalls under load. I checked compression, port side 120ish, starboard side 115ish, checked spark with inline tester just looking for spark. Not sure on motor function last time he took it out but he is seasonal so I'm going to say last year. The fuel is being premix and oil pump is bypaased.

Do you have spark on all 4 leads that jumps a gap of 7/16" on a test device, yes or no ?

Idk I don't have a spark tester that shows me the spark jump distance? I guess I could test them one at a time with a pair of insulating needle nose?

Perhaps look into getting your money back.

Well that was no help.

Buy (or exchange for) one of these at an auto parts store:

I can not see , hear or feel your motor.------It is up to you to answer the questions / do the trouble shooting.------To answer with ---" I don't have a tester "---- is nonsense and does not help you in any way.----So get a tester or run to your local boat repair shop.----Yes I can be blunt sometimes.

okay to answer the last comme

nt I didn't have a spark tester at that time, now that i have one the answer to your question is YES the spark on all 4 is at 7/16 and appears to be strong.

thank you oldboat1 for the pic that is the one I bought.

Water in fuel can cause this. I'd start by siphoning some gas out the tank and inspecting it in a clear glass jar. If fuel is good we can move onto other possibilities

 

[ellishe1]

Okay I'll check, and get back.

Okay update, went to tge ramp today to test the johnson 140, and it did fine so I guess cleaning tge carbs and I found a broken spark plug wire and had a spair, all is good thanks for your help. Now to start the boat restoration. I'll post updates. I think I got a good deal at $2000.
