I bought this motor back in July and installed it without any problems, went through the break-in as stated in the instructions.
After break-in I ran a couple of quarts of Valvoline 2cycle oil which was about a tank and a half, top speed was 51 mph on a Garmin GPS. Then I switched to Amsoil interceptor [I changed to pre-mix with this motor as my oil pump went out on the last one] after the first half a tank, speed went up to 53.3 then to 54.4mph.
Yesterday 8/23/06 on the second tank of pre-mix 50:1 my max-speed said 56.4 mph on the GPS.
Is this normal or can the GPS be wrong?
I have discovered I get highest speed in a light to medium chop in a head wind,
smooth water seems to drag the ski down some.
I thought about getting a solas concord impeller,which pitch should I get for a good hole shot as well as better top-end?
Thanks again for a great motor!
