I was racing with a 4 horse with a drilled exhaust
lol. goes well for 4hp must be the exhaust... what kinda knots you seeing. hoping to start basic races next session and wondered what im up against.
really nice coverage tho.. well done
It has a bow tank but we didn't use it for that race. We tried a new prop (26P thru-hub cleaver) and liked it quite a bit. 6800rpm and roughly 72mph. We used to run a Yamaha drag-copy but will stick with the thru-hub cleavers from now on - with the Yam we used the bow tank. Hull is from 92/93.
Yam copy was a 27P. From what I've seen I'd try to find yourself a nice cleaver and go from there. We have two Winrace thru-hub cleavers (23 and 26P) as well as a 27P over-hub cleaver - all are better all around props than the Yam copy we have. With the 23 Winrace we were well above 7k. We run the motor on a jackplate. 20" mid. 2.00 CLE gear case. The Yam copy makes the bow very flighty and so we're always filling/dumping the bow tank. With the cleavers we don't fill the tank (no need to due to extra stern lift) and so that might be a better/cheaper option for you to consider. The over-hub gave us an extra 1mph over the thru-hubs and 2-3mph over the Yam copy.
