yes, thank you for allowing me this oppurtunity to gleen some insight from the pros. my 50 hp force is an 86 that ive had since 2009. the engine hours said 10 then and now stand at 120. she cranks and idles ok but has no power. this occured , out of the blue . ive tried new plugs, to no avail . i posess a the origional service manual, and parts catalogue but am hesitant to touch much. semi retired, handicapped and unemployed have forced me to look for solutions outside a normal trip to a marina. can yall espouse?
