When I was pre-mixin', I used an ''Accu-Mix'' bottle...lines on side of bottle tell EXACTLY how much oil to add for the gallons of gas you just put in...there are some other brand names that look and do the same...$3.99 ;)

hmmm i took her out for the first time yesturday with my new prop 15x17 and she ran goood
top speed was about 32mph no slippage and the tach was about 5700
but how come you guys get moor speed than me
try i need to paint the bottom but maybe i would pick up what 2 mph more

Re: prop survey
 

Paint is going to slow you down!!

When under way, trim the motor up to achive best speed!!
I can go from 30 to 38 just buy lifting the motor, just becareful , the goal is to get it up with the least amout of resitance, but to make sure your still in the water, if you come up to high you will hear the motor rev!

My best with a 175 hp is 40 but I am alone, with a light load!
Most of the time full boat I go around 30 and top at 36 like you.

Goes real nice slow like 28 or so!!

MJ's right as usual..paints SLOWS a boat by adding resistance to the flow goin' under the hull...

W/my 150 WOT(6000 rpms) and trimmed to max(and still bitin') GPS shows 42 and cruisin' about 32... ;)
