Hi All,

I own a 3 meter Hypalon (rubber) boat, on which a '76 Johnson seahorse
6hp is mounted.

Whem i'm the only one in the boat, and I accelerate, the front of the
boat rises very high, and no speed is gained. When I move myself to
the front and accelerate, The nose rises, lowers, speed is gained, and
the boat is planing. As soon as I move myself to the back, the nose
rises, and I must to be carefull not to take off

When there are two people in the boat, the nose wants to rise, but the
engine lacks the power to overcome the drag created by the extra
weight of my passenger.

My outboard is in (nearly) mint condition, and the enginepart is not
definately not worn out. I had it recently checked.

I now wonder: would a modern 4 stroke 6hp do the trick for two people
in the boat? I think that "my" 6hp is measured on the cranckshaft,
wheras (for example) a modern mercury 6hp is measured at the prop. I
also think that modern engines just perform better. Am I right?

I do know that for example a 15 hp engine would do the trick easily,
but that is not an option, for I deflate the boat after every trip,
and I need to take the outboard on and off whilst the boat is in the
water. Since i'm not the incredible Hulk, a max weight of about 30kg
seems enough for me

Please advice!!

Thanks,

Ronald
