Etec 115 hp shaft extention question

Kbay:

If your at all handy and comfortable with dropping your lower unit, you can complete the installation yourself and send in the warranty card to Bay MFG yourself (comes in the box).

BAY MFG is a small operation (the wife of the owner will answers the phone) and they are very easy to work with if you have any questions or need replacements parts.

Installation of the extension on the two motors that I installed a required that you slightly ream out the midsection channel for the input shaft to allow the shaft extension to pass through and remove the shift rod to insert the required extension. The rest is pretty straight forward.

Kamikaze,
I have no problems dropping the lower unit and changing water pumps etc.. What do you use to ream out the midsection so that the shaft extension will fit through? It may become obvious when it arrives but I have never seen the extension kit so it is new to me.

Thanks

Kbay:

I remember correctly it's a 1 1/8 inch hole that you'll need to mount on a 16" extension ( I used 7/16" thread rod for the one I made). You'll only need to remove about 1/8" of material from the midsection casing to allow the Bay MFG 5" input shaft extension to pass through to the power head. The opening of the midsection shaft tunnel is large enough near the lower unit for the extension to fit, but the tunnel constricts near the power head, thus the need to enlarge it to allow the extension shaft to reach the power head. ETEC's maybe different than the older models I've installed the extension on, so I'd recommend you verify with Bay MFG to make sure what is required.

I see you live in Hawaii. I am on my way to Ohau for 2 weeks of work related travel. If you live on Ohau and need a hand just PM and I'll send my cell#. I'd be happy to lend a hand if needed.

I would make the dealer install the kit - just to avoid future
warranty problems.

Late update, I got the extension kit installed. It wasn't too hard but there were some tricky parts to it. I made a document with photos of the process incase anyone else needs some guidance as the instructions from Bay are very minimal.
