I’m converting a nitro boat to FE.It is the Punisher boat (40” v-hull) seen in my gallery.I have a 1200kv 45mmX77mm BL motor for it as well as a 120amp USB PC programmable ESC. I’ve found a cooling jacket for it from offshore electrics and a cooling jacket for the ESC from the same as well.I currently have an Octura x452 2-blade prop and will either go with 6s or 8s LiPo for power.

My questions are:I’ve used liquid electrical tape on my big boats trolling motor to water proof connectors; I plan to shrink wrap the ESC to the water jacket then add liquid electrical tape to water proof the ESC.Is this advisable to water proof the ESC?If not any ideas?Second,Since the hull is set up for a Nitro engine it has an open deck.I thought of buying a very light sheet of plywood, molding it to cover the open deck, then fiber glassing over it to make it water resistant.Or can I just leave the deck open with the motor catching ram air for further cooling?Third, the motor I have has a 6mm shaft I’m having difficulty finding a coupler to couple the motor to a 3/16 flex cable.Offshore Electrics has a suitable coupler but of course they are out of stock.I’ve found a coupler at this site:http://www.greathobbies.com/productinfo/?prod_id=GRA346Will this coupler be able to handle the torque of that large BL motor?If not any suggestions to websites that might have suitable couplers?I’ve checked a lot of sites:Offshore ele; Fuller’s FE; Tower; Horizon; Prestwich; ebay;etc, etc.Or could I break out the old Dremel tool and cutr the shaft down to fit a 5mm coupler?

Lastly,I have 5” rails on the boat.Offshore electrics has a suitable motor mount but AGAIN, it is out of stock.Are there any other sites that might have suitable mounts for 5in rails?The boat still has its nitro mount on it.I’ve thought of modding it to fit the BL motor by breaking out my brazing/cutting torch and connecting a standard electric motor mount to the old nitro mount either by brazing or by bolting.Comments on this?The mount is from Dumas and was for the OS Max .65 vr-m that was in the hull.There are the pics of the hull with the .65 in it.Suggestions/comments are very welcome!Thank you.
