Snapperd1, Thanks for the offer on the 80hp. I'm thinking it would be to large. Dragging the extra weight and turning that large lower unit is going to impact efficiency. I've got the coupling's covered. The wife's uncle is a suit at a coupling manufacturer in MD. He supplied the one in the picture and the price was right FREE. Stripperone, I haven't purchased the new motor, I'm still weighing my options, The motor is from a Co. in N.Y. D&D electric motors. They specialize in golf cart motors, they have and will build motors for custom applications. The motor that was recommended is a 5hp and was told it would operate at about 120amps. I got a price on a three blade prop. for the current set-up $79. Thinking about changing the prop. ,maybe the solenoids, then evaluate the results, meanwhile keeping a lookout for a 9.9hp lower unit to put together a new motor combo. I've seen Ray's electric motors, the expense it a little much for me to justify. With 5-6k I could finish my car or rework my pond.

Striperone, I'm using a solenoid set-up at 24 and 36volts. Doing some investigating I have found a 3 blade prop. available for the current lower unit. The cost is about a $100, but I'm hesitant to spend that not knowing if I'll see a noticeable increase in speed. The 9.9 Yamaha sounds interesting, but I'm thinking it's going to be cost prohibitive, trying to improve with minimal expense. The new electric motor is $625+shipping. Add to that all of the unforeseen expenses and I'll be at $800. I'll keep my eye out for that 9.9 Yamaha. Is there a benefit using a standard 9.9 over a 7.5 or 8hp? Thanks for the replies

Hey Steve, I purchased the boat, motor and trailer last year from a local man. He purchased it approx. 10yrs earlier from another local, they both fished it in Liberty. The man I bought it from owned a plumbing business and most recently(5-7 yrs ago) used it to install water pipes under the piers in the inner harbor. I don't know the thrust rating, tag on the motor rates the hp at 1.5. Although it moves the boat well, I'm not impressed and I'm looking to improve it. I found a co. in N.Y that I can buy a new electric motor rated at around 5hp. The representative said they could make additional modifications if it still wasn't fast enough. The down side is the faster you go the more amps you draw which translates into more batteries. I'm considering picking up another lower unit and building a entirely new motor with some different prop options. PS The appearance of the boat, motor and trailer now do not remotely resemble the condition when I purchased them. The boat was typical goose sh** green. Paul

here's a picture. I had to size it it looks stretched

I have a 14' jon boat with a 36volt golf cart motor mounted to a 1959 5.5hp evinrude lower unit. It functions fine ,but is not fast enough. I'd like to step up to a 48 volt motor. My ? is if I just replace the 36v with the 48v am I going to get max benefit/efficiency or would I be better served getting a newer lower unit. The 5.5 has a 2 blade prop. with no interchanges. I'm thinking if I went with a newer lower unit there would more prop options and I might see a benefit in a prop change. I live in MD. is there a shop/person that builds/works on this style electric motor set-up. My understanding is this set-up pre-dates the commercial electric motors that are popular and $5k. thanks Paul
