Hi.
I am new here.
I have been on the Honda outboard forum for a number of years, but am now the proud owner of a sail boat and in need of assistance.
A bit of background.
I am a Kiwi living in Denmark, where I live its only a 5 minute bike ride to the marina and the Baltic. I have owned motor boats for a number of years but have finally taken the plunge and brought myself a 31 foot sail boat. She is Boström B-31 an old girl from the mid 80s.
I brought her only at the end of the season (a couple of months ago).
She has a newly renovated 1GM10 motor in her that starts well and looks to be in good shape.
But i feel the motor is not coming up in revs while in gear there is water coming out of the exhaust and also a lot of black soot/sludge. The motor is so useless that she will not push my boat at all, the tiniest bit of cross or head wind and i am blown onto the pilings.
I hauled her up for the winter 2 days ago with a friend who is a experienced sailor. He has never come across a boat that has so little motor power we literally hopped from pile to pile to move her into place. his assessment was that she is not coming up higher enough in revs i don't have a tach on the panel so its hard to tell but i suspect he is right.
Here's what I do know.
The motor has been newly renovated, I was informed everything was done from top to bottom.
The gear lever works in reverse to normal ie i move the lever back to go fwd and vice versa. i was told when i brought her that its is because the old motor gear shifter worked in reverse to this one & to change it to normal needed an expensive adaptor plate or something so the previous owner decided it wasn't really a problem. This makes me think that maybe the prop has the wrong rotation But that besides shouldn't make the biggest problem as the fwd and reverse gearing are (i think) the same.
When i lifted her out the prop had huge amounts og growth that will of course not help the problem.
Thats all I really know, she is now out of the water so testing is not really an option but all other work/ checks can now be done.
All help will be gladly appreciated,
I'm hoping my problem is something small and inexpensive.
Many thanks.
Dean.
