Re: What makes for a ‘racing’ lower unit?

[benchrascal]

Some bathtub racers in Nanaimo BC experimented with racing units on their 6hp motors .Not sure now but at the time that was the top hp allowance .I could not believe how small a profile an lu could be and what high thrust you could get out of just six horsepower .Some of those bathtubs really fly .The one thing I saw that was common (irregardless of make ) was that they were all direct drive to reduce size and weight.
