Re: [bolger] Martha Jane outboard
Weight of the mj? I think others probably can answer that better than me -
I've never weighed mine - but I have lead and sand for ballast instead of
water ballast. I think the standard mj is about 1500 lbs - the new rudders
weigh a bit more -and the sponsons are additional weight. If the high house
is added that adds some too. Steve

1400 lbs. according to Common Sense Boats:

Greetings,
I had an old Honda 7 1/2 on my Long Micro and it was ideal. It pushed the
boat to hull speed at about 1/2 throttle and was very economical. I wasn't
going to use it as it was a short shaft but it is all you need as once you
have way on the stern wave ensures that the leg is well buried. I'd expect
that this would be similar with the Martha Jane.
When it was stolen I bought a 4hp Yamaha. It is light enough to lock away
but I've never seen more than 4 1/2 knots. Into the wind try 3 knots. Go for
power.

Hi Peter - I have just purchased a honda 8 hp for our mj ( Landroval). Also I
just completed the sponsons and the new rudders, ballast increase, boom
gallows and three part purchase on the leeboards - a major overhaul. I used
to have a honda 5 on another boat. I like the 8 hp so far - we've only been
out twice. I am still a bit concerned about the weight back there - I
estimate the new rudders to weigh about 110 lbs - add the 8 hp honda and you
have quite a bit of weight. My thinking was that there is only 17 lbs
difference between the five and the eight - the 8 is a much nicer motor -
being two cylinders - very smooth powerful and quiet. I do think the 5 would
provide plenty of power however. The short shaft works fine - I think (
qualified). The additional weight really does lower the boat back there and
it sits pretty close to the water - There may come a day that I raise mine a
couple of inches - but it will still work fine with the short shaft. I can't
speak to how it clears the trap door style rudder since I have the new
rudders. For me the verdict is still out on the new rudders - I don't have
enough experience with them yet to say who I feel about them - Steve Anderson

I had a Martha Jane and used a 5 h.p. Honda 4-stroke. This motor was able
to push the boat at hull speed with little more than half throttle; so I
think it would be able to cope with the tidal currents as well as a more
powerful motor. But the boat was unable to motor directly into a wind much
over 20 m.p.h.

My Martha Jane is almost complete and I need an outboard. Although I
intend to launch it in standard form - I don't feel like taking to it
with a circular saw at this late stage - can anyone let me know if a
short shaft outboard is OK with the new revised rudder set up? I have
just found out about these mods and there has not been time to get a
set of the new plans from the US.
I would like to keep the outboard as low as possible so I am reIuctant
to get a long shaft to cure the present rudder-outboard interference
especially if later when I get the motivation to do the mods this
would no longer be a problem.
The Aussie dollar has taken a nose dive in the past weeks and I would
like to purchase the outboard before this depreciation takes affect.
I would like four stroke. For weight reasons I am leaning towards the
5 Hp Honda but wonder if it is powerful enough and should go for the
8Hp. The area around here has 2-3 Knot tidal currents.
