Yammaha 2000 50hp 2-stroke vs 2003 50hp 4-stroke???

[renegade15]

So I currently have a perfectly good running 2000 C50TLRY 2-stroke with a 2003 powerhead (warranty replacement) that I bought from the original owner last year that used to be a yamaha dealer. I know the history of this motor and it has been great, runs great, regular maint items and a resealed lower unit so far have been the only service items. All of a sudden there are several 2002/3/4 F50... 4-strokes out there in my price range, especially considering I'd get a decent chunk of cash for the c50.

My question is if I should consider switching over to a 4-stroke? Were these years of carburated 4-strokes bad/good for any particular reason? I realize I will be adding about 50 pounds and losing the 2-stroke get up n go...but i would really like to be less smoky and not have to always be mixing oil...we're out almost every weekend and it's not a big pain, just something I have to always remember to keep on hand. I rent a lot of boats for work and have really been enjoying the 4-strokes as of lately, seems like most of the rental fleets are either yamaha or suzuki 4-strokes now!

I know the 2-stroke will last many many years and I do enjoy the ease of working on it, but the non-injected 4-strokes don't seem terribly complicated either.

Any opinions?

The boat is a 15' renegade flats skiff, not a heavy boat.

Well, mine is a 1999 Yamaha 90C, and for the lighter weight, simplicity and power, I'll run it 'til the cows come home. My son runs a Yamaha 115 4 stroke on his boat and he thinks it's the greatest thing since sliced bread. Just all depends on what you have, want and need, but I'll be keepin' my old 2 stroke!

I do not know much about the F50,
but have heard the F40 is a tough motor to sync carbs properly need special equipment and passages are small , so plug easy

find out more about the F50 before buying

I would not swap motors ONLY to get the four-stroke and lose performance in the process. If you find a similar deal on the EFI engines then you have a reason to swap (although there is still the performance issue).

Considering they're both the same hp and the fact that the 4-stroke undoubtedly weighs a lot more, it seems like you might actually decrease your performance by swapping over. Not to mention the increased cost to maintain/repair the 4-stroke. Most Yami 2-strokes in the 20-50hp range are worth their weight in gold down here in FL.

I was set straight by my mechanic, whome I also asked this qestion. Stick with the 2-stroke, one of the best motors out there especially for my boat in the environment that I use it in!
99yam40 is indeed correct, the carbed 4-strokes are much more difficult to sync, and they are also just in general way more finicky than my c50.
KFA, I know what you mean, I was given an incredible deal on this motor, and it really has been great after blowing up 2 omc's in 3 years! I just figured I'd see what my options were, and turned out my best option is to keep what I've got

Thanks for the input though!
