Don't forget to deduct of 3 + 1 gallons of oil, oil tank and plumbing from that 100# difference. If you like quiet and or trolling go with the F200-F225.
I have come to the conclusion that the biggest deciding factor between the two is PRICE! All of the 2 stroke owners are always saying how much more power their motors have. The 4 stroke owners, like myself, are always listing all the "other" benefits of the 4 stroke, like no oil, no noise, etc. I think it is great you have two choices from Yamaha to pick from, with either being a great motor! I will be the first to admit a power difference, but, the difference is minor unless you are really concerned about a guy in the same boat being a LITTLE quicker! Get the 4 stroke! Without even talking performance numbers, you will love everything else it offers! The performance difference is too small to notice and in my opinion, doesn't mean anything anyway unless you are in a Bass fishing tournament and need a Bass boat that runs 60-70 m.p.h.
parker the biggest difference is not top end speed..because in most cases for saltwater use the top end spead is not a factor& even if it were it's minimal like 2 to three mph.the biggest difference for me is the low & midrange power & the a di two stroke helps me get my boat on plane carrying a heavy load better.for others it may not be a big deal.both are good engines & both are good on fuel & both are quiet & both little to no smoke.people need to buy which engine is better for them.
They are unbelievable motors. You make adjustments for the difference in power, but the quiet, smoothness, efficiency, they cant be beat. Just get them.
I have owned outboard powered boats most of my life. I switched over to 4-Strokes 3 years ago (F115 Yamahas) and all I can say is "I'll never go back to a 2-stroke engine"
SCAngler, I wasnt' only refferring to top end speed as all the performance specs I have seen show minimal differences across the board. On my Parker the difference to plane is around .4 seconds!? .4 seconds is a matter of 10-12' to 30 m.p.h.between my boat with the four and the same boat with a 2 stroke! I realize it will change in large, higher power boats, but still, they are not dogs by any means. For anyone to give "seat of the pants" comparisons, they would have to rig the exact same hull, one with 2's and one with 4's, the same h.p.,at the same weight,and the same weather conditions to give an honest opinion. There may be some rigs that feel underpowered, but I have been in 2 stroke rigs that "felt" that way also.
Like I stated earlier, it is nice to have two choices in Yamaha power and I do agree you can't go wrong with either. I would be very curious to how many people who post about 4 strokes have ever ridden in a boat that had one or more! I was a Yamaha 2 stroke owner and cannot tell any difference in any range, low/mid or whatever. This power/torque argument will go on forever and there is a difference, but, it's just not worth picking one or the other over it! IMHO
Paul at BW said today that he wouldn't rec the 4 strokes (twins) on the 2550 b/c of too much weight...A single can do but I want twins...looks like it's the HPDI's!
OK so the four strokes dont CONSUME oil,,(when new) but you have to change it and check it...and alot of todays boaters dont know how to even pull the cowling let alone have trailers to pull the boats to change the engine oil I guess the engine oil can wait 100 hours plus like the gear oil has to do....

Lived at The Breakers' for 3 years a few years back. Windsurfed out front of the pier alot. Caught some King Mack's and love the Flounder Lounge! I miss that place alot and hope its still the same. Way to go on the 4-strokes!

Besides lbs, 200 Yam HPDI vs 4 stroke?
For me it was personal preference, I had a 200 hpdi on my 21' and I liked it so I went with twins on the new Whaler, could have had F200's but I like the hpdi's.
Love the twin HPDIs ( 200s ) on my Grady. Nearly smoke free, quiet, and great power throughout the rpm range. A buddy got a 2800 Hydra w/twin 225 4 strokes and with full live well ( transom ) couple of guys etc. he said get up and go was an issue ..
I get 2mpg and the Grady site with perf specs on the 2 /225 4strokes shows the same thing. Given the relative short time on the market, is the verdict in on the 4 stroke longevity? Running so high on the rpm range?
