Re: [bolger] Re: Transom alteration for a micro
I had the same problem with my micro using too large
an engine to start with. I had it on a bracket. The
big engine really messes up the sailing
charactaristics, putting weight to far back. It
causes hobby horsing and lee helm and lousy pointing.
A Honda 2 would be fine for a micro. I used a Johnson
1.5 for a while and it did fine.

Martin,
No,it does not flex.Also,there are two small knees intalled
longitudinally(fore and aft) which lock the top piece of the transom
in place.When Phil Bolger visited my boat in '93,he commented
positively on the elegance of my solution to the too small outboard
opening and sort of confessed that he did not recall why he had made
it so small in the first place as this greatly reduced builders
options in outboards....
However,depending on where you intend on sailing(sheltered lakes
VS open water with currents etc) you may not need alot of power.You
could always sell/trade your present outboard for something smaller if
you will not be sailing her in currents.I do all of my boating on a
river,just upstream from some mighty fine rapids and enjoy the peace
of mind the extra power provides.
Also,do keep Johns comments in mind,Bolger is a master and it
does not take much alteration before you hatch a whole series of
problems which you alone must solve and may end up with something not
exactly like the designer intended.The transom issue is,however,a safe
move.

Is the Transom really a MAJOR structural element, when about 20" in front
you have another bulkhead that is just as solid?
I have no option but to use the motor I have as I bought it with the bought
and the chairperson of my finance committee would not approve of changing
it. A rough measure indicated that I would have to raise the aperture by
about 3-4".
Has any one put a metal strap across the gap, if so any photos?

Martin,
Our MICRO was completed over 10 years ago and has many (nautical)
miles on her.
If your suggesting removing all the material above the hole which
passes over the top side of the 'engine hole', it doesn't take a
naval architect to see that you're going to loose a MAJOR structural
element.
If you've built other Bolger boats, you know that Phil is the "Master
of Minimization" .....if a piece of wood is on the plans, you need
it. You take off a piece and you can be sure that (for the same
strength) you're going to be putting on a lot more than you took off.
In my opinion, you need to minimize engine weight. Remember that
just a couple of horsepower will push the MICRO at near hull speed.
Good luck with you mod(s). Main thing -- have fun! It's a great
design.

Martin, I did exactly that, and put in a strut each side back to the
first bulkhead, and probably stronger than the original.
I fitted a rope traveller across the top of the same deck bulkhead
and it all worked fine.
Other methods mentioned are probably just as good.

I'd advise against just cutting that wood away for two reasons. It
provides a lot of strength and stiffness to the transom and moving
the mainsheet would change your ability to sail on different tacks.
I had a 4 hp motor that was a bit too big for the hole, so I used a
2x6 for the transom cap and cut away about an inch of it in the
middle over the engine hole. That way I still had a one inch board
going across the transom and could still sheet my main amidships.
You could simply cut away what is there and build up the center
section to whatever height is necessary, just keep your transom
strength and sail geometry.

Having purchased a micro and an engine (honda 4 stroke 5) I wish to move the
engine on to the transom instead of an ugly bracket. I popped into Classic
Marine which is near me in Woodbridge in the UK, and Moray asked 'Why not
just remove the wood that goes over the 'engine hole'. This would leav
great access to the motor and would only require a small change to the
sheeting position of the main? Any reason you lot can come up with as to
