just a little info for all
yes i agree with you, i have replaces the shaft for the second time in the 5 years that i have owned CLEO
the cost was £65 from yanmar at Burseldon(top of Hamble
and not too difficult to replace.
the mechanics in Marine power are very helpful and let me use their vice to hold the fitting and were helpful in the correct way to remove and reloace the seals etc.
