1989 Force 50 HP

[tiller7104]

I am in need of someone who knows his way around a 50 Hp. I believe the wrong plugs are in my engine now....can anyone tell me the correct plugs to run or at least where I can start? I am also wondering what you guys suggest for a fuel to oil ratio. I have been running 50:1 but it smokes a bit...but that may go full circle back to incorrect plugs LOL HELP Thanks in advance Stuart

NGK BUHX stock number 2522<br /><br />Should look like this:<br /><br />

<br /><br /><br />You can substitute with a Champion UL18V

And yes 50:1 ratio.<br />Using synthetic oil will help with the smoke.

Roscoe thank you very muck for the info! Is this engine a historically an unreliable engine? I am trying to see if this engine is worth keeping or not? I am very good with the wrenches and don't mind tinkering but I fish a river with this motor and the current is swift if it concks out I am down the river without a paddle LOL! Thanks in advance.

Not the most reliable.<br />Easy to spin a prop hub, sometimes just from accellerating hard.<br />Electric components can be troublesome.<br />Lower unit, waterpump, and fuel pump needs to be maintained annually.

Roscoe what maintenance is needed yearly on the waterpump? you mean a new impeller ? just did mine last yr., what other maint on the w/p<br /><br />also what maint. needs to be done on the f/p yearly?<br /><br />and one other thing I have a 89 50hp, where can i find the insulating foam inside the cowl, the old just completely went to powder.<br /><br /><br />Do you use synthetic in yours and which brand.<br /><br /><br />lot of questions, i know lol<br /><br /><br />thnx<br />mark

Re: 1989 Force 50 HP

Ok you caught me in a typo.<br /><br />Fuel pump needs a new diaphram every 5 years or so.<br /><br />Lower unit needs new lube every year, or sooner if you have a leak.<br /><br />Water pump impeller every year or two.<br />May need a whole new waterpump housing if it is showing excessive wear.<br /><br />OIL - usually get Pennzoil full synthetic, $20 a gallon.<br />I have used AMSoil HPI , but it is not TC-W3 rated, so use at your own risk.<br /><br />Don't need any special foam for inside the cowl.<br />I know guys that just used some 1.5 inch thick eggcrate foam, get it at a fabric store or craft store. Attach with spray adhesive, its like rubber cement.
