Replacing the Engine and Need PropHhints

I saw a MD3 engine for sale and wondered if that would fit in the space for the MD2B instead. About ten horses more and that would really push her along.

md 3b may be the way to go,as a lot of the parts off the md2 are the same,would reccomend a new shaft if corroded anyway,plus may want to change pitch on the prop for the bigger engine.

though becareful about exchanging one engine for another non runner!

No not a bad guy at all. I am looking to for a storage space for it now but money is tight these days. Still I wonder what the line at the top of the stuffing box is for if it is lubed from behind it.

I think the tube is to allow water pass into the stuffing box packing, so it stays cool. The tube you're talking about should terninate above the waterline. The other way that same process is done is to cut slots into the the side of prop tube area between the cutless and the stuffing box.

the tube to the stuffing box is for water cooling/lubrication,normally tee'd
into the raw water just below the anti siphon so water is pumped through it
and the exhaust,and so as not to flood the engine once stopped.

some stuffing boxes have the same set up but with grease boxes,to force grease into the sterntube and bearings.

I am seriously looking at a electric motor set up for propulsion. I found a D/C motor not cheap but reasonable and a I can get a controller at a reasonable cost also. But I was wondering if I should change the polarity to change prop direction for reverse or should I add a trans on the back end of the motor? I have to do more research on that aspect of it. I think a trans on the D/C motor is the best way to go there.
