need more info
yes a 9hp is big for your boat, but if you run in fast currents, headwinds, or big seas on the bow the extra hp would come in handy I think. A 6hp extra long shaft would be just right. You need the extra long shaft to keep the motor in the water when you go forward, or with choppy sea conditions. The 9hp would be heavier and harder to take on and off, or tilt up when sailing. You don't mention if its 2 or 4 stroke? I like 2 strokes for their lighter weight. I had an 8hp 2 stroke sailmaster extra long and an 8hp 4 stroke high thrust extra long shaft. The 2 stroke was a whole lot easier to lift on and off the bracket by myself, the 4 stroke took 2 people struggling to do the same thing. I used them on a #4500 oday 25 and they were plenty powerful for all that I did here in the central gulf of mexico. The boat will only go so fast under power no matter how much motor u use, hull speed. I too used a seagull, in fast current I could walk faster sometimes with it maxed out. The bracket mount is another issue to deal with, can it handle the extra weight. I can't remember if you have a well and transom to mount motor or if mac21 uses bracket.

Thanks for the information. I was thinking it was a little too big, but wanted to get input from someone with more experience than me. My Seagull works ok, but at times it seems a little under powered. Also, it would be nice to have the ability to turn the motor 360 deg. or have a reverse.
Once again, thanks for your help!

I use to sell and saill them many moons ago. I think they were last built in 1986.
Suggest no more that a 5 or 6 hp.

which outboard
Ive got a pearson 26w at 5200 lbs displacement a lot heavier than your 21 footer I recently replaced my 20 year old outboard with a Tohatsu 8hp long shaft 4 cycle I thought it was the right size but It weights 83 lbs and Its too heavy for me. I have never run it over half throttle
AS its much more powerful and heavier than the old 10 hp 2 cycle It moves my boat at hull speed at less than 1/2 throttle. Think carefully before you select something to heavy or powerful

I have an 8 HP Johnson Sailmaster on my 222, and its about perfect. I sure wouldnt want anything smaller, and its heavy enough already. Previous owners had a 6 HP Sailmaster and complained about its performance into the wind.
Dale, All things to consider being said before, Unless you're expecting to deal with strong tidal currents or heavy seas the 9hp will be too heavy. While I haven't seen a 2strk 9hp, the 4stroke would be tough on the bracket(my 4hp requires some effort to pull up from lowered postion)unless you really reinforce behind the transom as I did. What hasn't been mentioned so far is your V21's pointing ability with that much extra weight on the stern.
I switched to the merc 4 because I,too wanted neutral & reverse and my old 2strk didn't have it and I could actually notice the difference in performance when pointing when I brought the merc up and tilted it forward and thus shifted the weight ever so slightly away from the stern.
