4 Stroke Weight vs. 2 Stroke on Bracket

[RidgeRunner]

The direct injected 2-strokes weigh more than the old carb motors. The confusion you may be experiencing is that most 20v had the lighter carb motors from birth. When you step up from there to the 4-stroke it is a huge difference in weight. Example

I have a 200 carb Merc 2-stroke that is fairly light at 389 lbs.

The smaller Verado 4-cyl 200 4-stroke is 510 lbs. The 225 6cyl is 635 lbs.
The Merc 200 Opti 2- stroke is 497 lbs.

Right now the bracket on my 20' cc is riding pretty high so I don't think I am getting any bouyancy from the bracket. I don't have a self bailer so I can't help you answer the bailing/not bailing riddle.

I might be happy with the performance of the 150 4-stroke but my wallet has decided to go with a rebuilt 250 EFI in the next few weeks at 475 lbs. I would be happy to share some images of how she does with the extra 90 lbs. Weight would be very close to the Yamaha 150 4-stroke.

My 20" Johnzuki 140 4 stroke is said to weigh 410#s.

I think it depends on which 4 stroke you are looking at and to which 2 stroke you are comparing it to.

The problem you run into with the weight issue on a bracket is the "moment arm." Sure 40 lbs doesn't sound like a lot of weight, but when you take that 40lbs and move it two feet further from the center of bouyancy it acts like upwards of 100-200 lbs. So, basically the farther you get from the CB the greater the "moment" is for a given weight. It's kinda like what a doctor tells you about picking something off the floor and bending at the waist: 10lbs puts 1000lbs of pressure on your lower back. The weight difference probably wouldn't be that big of a deal if you weren't using a bracket since the weight would be closer to the CB. Two strokes have more power anyway!
