Re: 1989 Force 125 Bored .30 over NOT RUNNING RIGHT!
Well, I removed all spark plugs today and did a compression test on each cylinder. I have 150PSI EXACTLY on all 4. It was as if I never even switched the checker from one to two and so fourth. The meter reading was precise on every one. I thought perhaps the meter was broken, so I left the dock and borrowed another checker just to be on the safe side. SAME thing! 150PSI Unbelievable compression...
Which leaves me to my final conclusion of sticking to the basics:
Compression: 150 PSI on all 4
Fuel: All lines are new, primer is new, replaced pump AGAIN, filter clean, WOT carbs are fully opened & synchronized definitely getting GREAT fuel.
Spark: Pinkish-Orange -------- Here is where my brain starts ticking...
A few people stated that they were getting the same color as me. I am going to go ahead and assume that their motors are all running well, considering that they are not complaining or inquiring about any problems.
There are few different "x-factors" that we all have to take into consideration though, x factors of both my boat and the others.
A) Boat size, weight
B) Top speed
C) Max RPM
D) Current compression
Lets assume that a motor with less compression would generally require a spark that was not as strong. Maybe at one point, when the motor was new, or even within the first 5 years of the motors life, perhaps it once had 150PSI and the spark was purple/blue/white. As the motor got older compression would be lost, naturally, wouldn't the spark get weaker as well? THIS IS JUST A THEORY any help to answer this question is very much appreciated!
If that is the case maybe since the compression is not as strong on the motors with the orange spark, maybe it doesn't need that strong of spark to run properly.
If I return the used components and order the new, this will guarantee the best spark possible. There would be nothing else that can be done. EVERYTHING would be brand new. I know this sound ridiculous, but I am running out of options. I can order all of the parts I need for $1800.00 including the flywheel (just to make sure everything is new) 1800.00 - $575.00 credit. The flywheel is the most expensive part @ $600.00. I'm getting impatient. It is either buy these new parts and it works, mission complete, or it doesn't work, I sell the motor (I'm sure it will do someone miracles on a lighter boat) and buy a used 150hp motor. If I don't try this last option and I never get it running properly, and sell the motor and buy a new/used motor, I am always going to wonder what would have happened if I tried to purchase a new electrical system. I would be able to rest assured that I gave 100% when trying to tackle this problem.
As far as the other X-factors, I think the weight of the other boats vs my boat would be important but I do not have an exact weight for my boat. I know that it should be close to what it was stock, maybe adding an extra 200LB for and extra battery and some stereo equipment. I checked the foam that I could get to in the bottom of the boat, without destroying anything, and it was all dry.
Let me know your thought,
Thanks
