Hi all. I currently have a ’59 Electric start 18 hanging off the back of my 11′ Aluminum boat. This motor has got to weigh close to 100lbs. I don’t how how exactly to weigh it but I have looked online and can’t find specs on it. It’s a little too much motor for the boat, but I have a lead on a ’52 25hp.

Anyone know the weight of either of these motors? Thanks fellas.

Im confused……which happens a lot, but the 18 is too much motor and you want to go bigger? Maybe im not understanding.

Anyways, the RD13 will weigh about 95lbs, and the FD13 -18hp will weigh about 77 lbs

I’m thinking the electric start 18 would be about 90 pounds (??) So, if weight is the problem, there wouldn’t be a huge difference with a hand start RD from early ’50’s. But don’t forget the heavy battery to go with the electric start. On the other side of the coin is the effort to start the 25.

Thanks for the help, fellas.

Yes, the 18 is a little too much motor but I’m having the transom significantly stiffened this winter and it should be a bat-out-of-hell.

The battery is no concern, I made a battery pack out of a pocket sized auto jump starter, a 12v switch and a starter solenoid from a Ford pickup. It’s small and will start the 18 all weekend with plenty of juice left to spare. It probably weighs 5lbs total. https://www.youtube.com/watch?v=gEHzaNv0kYw

If it’s only 20lbs-ish heavier, I think I’ll buy it 🙂

I have the 1954 Evinrude 25hp manual start as 98 lbs, the 1955 electric as 129 lbs.

For an apples to apples comparison, the 1965 33hp manual start is 127 lbs,
the electric start is 140 lbs.

sheesh, the starter isn’t THAT big on these things, where does the 31lbs come from!?

It looks like your primary objective is speed. While overpowering a boat may not be particularly safe, it gets done all the time. To really get your boat to sit up and take notice, hang a late Mark 25 on it. Manual start. No weight penalty over the 18 hp you have (and you have the right idea with the small battery!)

I guess you mean the numbers quoted by phil. It isn’t just the starter weight, the ’55 is a heavier motor than the ’54, with or without starter.

Every year the RD went up in weight a little. As I said, the RD in question was only 95lbs.

For weight, they add up the heavier flywheel, the starter, the wiring harness, the solenoid box, etc….

The weight of the starter can be counter balanced by moving the battery and fuel tank to the front of the boat. Use double aught welding cables for extending the battery. Even the 25 horse model of that 22 cubic inch motor was heavier to handle the additional horse power. Just swapping the powerheads would add a pound or two. . . 🙂
