Oh, I wasn't arguing with your assessment that it would be kind of expensive
for an older boat. I was just arguing about re-gearing.

IMHO a prop change would handle it. I know I can go from 80 to 150 HP on a
Merc OB with the same lower unit (2/1) and just prop changes - done it.

Clams,

Check out the hp/torque curves for the two engines. My failing memory
seems to
be seeing a lot of revs to make 188 hp with that old engine. I also seem
to
remember the older engine hp ratings were flywheel numbers vs todays at
the
prop numbers??? Or not!!! Maybe a prop change would handle it.

Even so, the project makes little economic sense unless it's all the
budget
will handle or there is a strong emotional attachment to the boat.

the difference was a little more drastic, I'd think a prop change would
handle it - no?
