hello all,
I have a few questions about my 115 mercury tower of power,its a 1985
1st of all I test ran the engine on my 1985 glasstream bass boat which is just a smidgent under 17 foot long,I left the original aluminum prop on the engine,I added 3 gallons of gas to the gas tank but i believe i added too much oil in my mixture,the tank already had 4 gallons of mixed fuel in it already,
the engine fired right up and i waited for a nice **** stream to come out,it did after a few minutes,then i planed the boat and off i went,at 5200 rpm the boat was hitting 58mph at wot, after i trimmed it up all the way it hit 5300 rpm and hit 62mph at wot, i drove about 3 miles and returned to the dock quite impressed with not only the quickness it got on plane,but the overall smothness of the ride and the speed of the boat,I decided to put on a stainless steel prop that came with the boat and after talkin to the mechanic who serviced the boat its entire life he claimed it was the right prop for that engine and he knew it cause he sold it to the owner,
well the next morning i fired the engine up and it was noticeably blowing alot more light blue smoke,i drove the boat about 3 miles at wot and it flew with the stainless steel prop on it,after returning to the dock when i tried to power up the engine it kept bogging down and stalling,it would rev up nicely in neutral but stall in gear when the engine reved,i got scared and put the aluminum prop back on,again the boat ran well for about 3 miles then began to bogg down and stall, is this due to too much oil in the fuel?
should i empty all fuel and start again with a true 50:1 mix ratio?
do i need to replace the spark plugs now?
did i screw up the engine?
was the stainless prop too heavy? ( its 3 times heavier then the aluminum)
thanks for any advice guys and look for the updated pix of the 90% completed 1985 glasstream bassboat
