Why not just place it on a scale and weigh it.
how can I get more power out of my 8hp evinrude Sell it and buy a stronger motor
75 to 80 pounds
About 70 lbs.
1992
The fuel to oil ratio for a 1988 model, 8hp Johnson outboard, would be 50:1, six gallons of fuel, to one pint of two cycle oil.
Not very fast at all because of all of the weight but the 150 pounds would almost even it out.
$600-$800 in fine working condition.
100/1Actually, it is 50/1. I have a '99 with the original owner's manual and it clearly states that after the break-in period (which is 25:1) it is necessary to use 50:1. No older motor would be different.As far as I know, only Yamaha o/b's use 100:1I own an Evinrude 8 hp 1986 and the recommended mixture is 100:1 but I always use 50 to 60:1 and so far no problem.Not only Yamaha my friend use 100:1 you should check your reference.Best and Correct answer: The 1986 4hp, 6hp and 8hp sailmasters are 100:1
Our Techumseh 8HP has a Champion J8C
think its the last 2 numbers of serial is year so 1980 i think
318cc. is 8hp. 305cc.is probably between a 6 to an 8hp.
An 8 hp Mercury, serial number B387142, is a 1989 year model outboard.
