ETM question

Postby JYD » Wed Jun 12, 2013 10:12 am

Hi gang,

I've got a project that I think would be perfect for the Glen-L ETM design. My problem is that I only have about 12 total inches of vertical clearance between the hull and the aft deck in which to fit the thing. Before I spend $45 on the plans and another $200 or so on a trolling motor, do you think that is enough room for this concept?

I'm not too concerned about water ingress as the thru-hull fitting should be sitting right at the waterline at that point.

Any input would be appreciated.

Thanks,
JYD

JYD,

The ETM plans show the motor mount to be 11" or "as required". So you know, this unit is not quiet like an electric motor--I think it's due to using the lower unit of the outboard...

Thanks for the response. Just to be clear, i was referring to design #410. It should be pretty quiest shouldn't it?

Yes, that is what I'm referring to and no, it won't be quiet like a regular electric motor.

I am amazed. I would have thought that would be pretty quiet if not noiseless.

I can see where the following could be quite noisy:

JYD, what HP are you thinking? I have a 1 HP DC motor I am doing nothing with.

Well, I was thinking about a 50lb thrust trolling motor, but now I'm wondering if that is a good idea.

I have to apologize here. My original comment about this being "noisy" was actually in reference to the Electric Drive (ED) NOT the ETM. So sorry for the confusion...
