I am a recreation area supervisor in California with limited background
in boat engine repair. We have a fleet of 60 rental boats for fishing
and cruising. They all have 4-cycle Mercury 6hp or 15hp motors. The
concessionaire, who runs the rental business for us, sent me a list of
problems - they conclude that all seem to be related to the operator
running the boat on shore, causing damage...OR, is this due to poor
maintenance?

Does anyone out there have advice for me...Please!!! Here are some
examples of the problems the mechanic has reported. THANKS!!!

#1 - Problem, frozen power head, broken pull cord assy. Lower unit
maybe good. Stiff when try to turn. Cause, impact damage from running
the boat to shore repeatedly. Need new power head. And pull cord assy.
And water pump rebuild kit.

#2 - Needs new pull cord assy. cause, worn out from constant use.
Broken carburetor. Plastic part on carb. broken off cannot be repaired
need new carb. Motor turns (not frozen) needs pull cord assy.

#3 - Problem, Lower unit bad. Cause, most likely repeated impact from
landing on shore. Pull cord assy. broken Need lower unit and pull cord
assy.
