Bought my first pontoon (1989) with a great 4 stroke engine, and loved it except for one thing. The rear supports for the hard top would make an annoying squeaking noise. Tightening the bolts would stop the noise for a while, then the noise would return. After dropping the top I found the holes...
I am looking to replace a 70hp force with a 2008 50 hp mercury 4 stroke. The mercury did not show water through the pee hole after running for a minute. I shut it off. The guy said it takes longer for a 4 stroke to warm-up and pee. Not ever owning a 4 stroke I am a little concern. Any advice...
Sorry it took so long to complete the post from august 23rd. Motor would not idle but ran great wot. Not sure which fixed the problem but the motor runs like new;; Resealed the recirculation cover, cleaned the carb, ( rebuilt the fuel pump - probably the cure). Thanks for the suggestions.
I have been working with a 1994 force 70hp off and on all summer. Had a problem with gas build up around the bottom cowl and carb. Looking to rebuild the fuel pump, I found a bolt in the bottom cowl. I found it came from a recirculation cover. replaced the bolt and the engine ran great WOT but...
Getting my boat out from the winter, I put a new impeller in the water plump but did no replace the base. It has been 6 or 7 years since the base has been replaced. Drain the gear oil and there was no sign of water. Cranked it up and had good water pressure and a strong pee. After letting the...
first time this year to use a boat and found the engine seemed lock-up. He said it ran perfect the last time out last summer. This is a 1992 70 hp. We sprayed some oil in all 3 cylinders and got the engine to come lose. The compression was from top to bottom - 120 , 60, 120. We did not attempt...
I have just completed a project and now considering another. I came across an older pontoon boat that is in fair condition. It has a 1976 mercury 65 hp. My question is how reliable are these motor?. I have never worked on a motor this old. Are they much different from the mid 80s mercury outboards ?
I have a '83 mercury 90hp that is bogging when full throttle is applied. It cranks ok and will run great at low RPM. A mechanic tell me the number 4 coil is irregular(jumping around) and could be causing the problem. I believe the problem is in the carbs. I have been through all three carbs...
last summer I had surgery and was unable to run the gas out of the tank. I used a treatment that prevents the separation e-10 fuel. There should be about 7 gallons of gas left in the tank. If gas has separated will drygas, or heet remove the water and could these additives damage the engine?
After months of working with a bass boat, I decided that the time and money was something I do not care to take on again. I was looking to buy another boat for a great price. From my last project I found that a good price could be a sign of problems. The floor(deck), the transom, and the...
I have a 1986 150 that seems to be missing at about mid throttle .This problem is not present during wot or running slower. Only at mid range. It sound as if is running out out of gas but when I open it up or reduce throttle the miss dissapears and it runs fine. Any ideas ?
Been messing with a 1983 90 hp for a while. Had it cranking and running good. Now when I pump the primer bulb it does not seems to get gas to the top carb. Before, during priming, it would show a little gas coming out the front of the carb and it would crank and sound great. Any ideas ?
I have a 1983 Venture that I have been working with for a while. The engine is ready, now I am looking at the repairing the floor. I was expecting the entire floor to be suppored with wood, but found after cuting the soft section away from the middle that holds the wiring and hose is the only...
I been working on a '83 90 hp inline 6 off and on for the llast 8 months. One problem led to another. Put a complete water pump in it and the base assembly did not seem to seal at the bottem. After completing the job the motor crank right up and it started peeing but I found water coming out the...
Have a 1988 xr4 that I rebuilt the carbs the spring of 2011. The manual said the carb adjustment was factory set. It is hard to tell if it running too lean because it has the flat plugs( no electro). Is there a traditional plug for this motor? The top of the pistons had a carbon stain with some...
Been working on an1988 XR4. Doing a few extra things on the cooling.I have had problems with it over heating. After replacing the water pump the pressure is still low (3 to 8 psi). Thinking of a way to flushing from the top down. Can this be done by adapting a water hose to top where the water...
Working on a 1988 150. The compression when the motor is cold is 120 to 119 when the engine is cold. After warning the engine the compression drops to 110 to 100. Which is the most accurate?
