I am looking for a used outboard engine for Mac25. What mfg/model/horsepower would you recommend? What size propeller should I use? Thanks in advance! J

Mac25 motor
We've used a Yamaha 9.9, longshaft, 4-stroke, electric start, with 14amp alternator and remote shift and throttle. A great engine. Drawbacks - 110 lbs heavy and pickup tube in carb bowl tends to clog.

what's the height of your yamaha
First, thank you for sharing your info! How tall is your engine? Jeff

Need power?
I have a 8hp Merc 4 stroke longshaft on my 25 and it is plenty of power to reach hull speed. In hindsight, I wish I had sprung for a 9.9 for the alternater and electric start. Mine is 87#. As far as the prop, get the largest diameter and lowest pitch that will fit, you are looking for low end thrust, not speed. I haven't heard of any significant difference between the Yamaha, Honda, Merc or whatever other than price and dealer service.

I have a Honda
I have a Honda 9.9 longshaft with electric start and alternator. It is a little heavy, 100 lbs or so, but runs like a champ w/plenty of power. Easy to pull start as well. I once had to tow a 21 foot cuddy cabin with engine trouble. Not a speed demon but plenty of power.

had both
My 25 used to have a 9.9 evinrude. It was a bear to lift and really I didn't need that much to get it up to max hull speed. I broke that motor doing something stupid and ended up getting a 6 hsp. mercury used. 2 stroke 2 cyl. Turned out to be plenty of power. I max out hull speed at about 2/3 throttle and will get me into 25 knot winds ok. I was initially worried that 6 wouldn't be enough but it is fine. I wouldn't want less though in case I wanted to battle a real blow upwind. Of course, that is what a reefed main is for. In a pinch, probably use both and tack up pretty good. 6 also is a lot lighter than a 9.9 but there is nothing wrong with the bigger motor. I would go with the best deal you can find in that range. Also mine cost 600.00. Its a '90 something in very good shape if that helps. Take care.

Merc 6.0
I purchased a Merc 6.0 four stroke last year, its a great motor, more than enough power, very easy starts for the wife as I like to be on the bow to pull the anchor once she fires it up, used to have an older two stroke, wow, even I had a hard time starting it. I like the 6.0 as its light enough for me to easily carry from the bed of truck to boat, even up a ladder when I stored it there on a recent move. I was sceptical about going with the four stroke, but moving to the Tahoe area, I heard you had to have a four stroke on that lake, I sure am glad I went that route, its a nice motor, brand new, and still got a good deal, even through West Marine, probably could have gotten it cheaper elsewhere, but the bonus bucks came in handy later for the stereo that I put in.

2 or 4 stroke?
The newer 4 strokes are terrific. If they're too pricey try a used 2 stroke. Do look into the areas you plan to sail for restrictions. The 2 stroke bans will become more noticeable in the not too distant future. I highly recommend the Nissan or Tohatsu motors, they are very good, easy to start and give no trouble. Steve

Mac 25 motor advice
I just finished my first season with a Mac 25. It is a 1976 but has been beautifully painted and refinished. I have a Evinrude 9.9 (2-stroke) with electric start and alternator. It seems to easily push the boat at hull speed. It is heavy to lift up on its transom bracket. I set up a pulley system to help out but it's still a pain to pull it up and release the catches at the same time. I would be interested in knowing: 1) Will a 9.9 4-stroke be a lot quieter? (i.e. is it worth the extra money to upgrade?) 2) Should you be able to easily lift the motor on a modern day transom bracket. (mine is probably original equipment and has very little spring assist)

Lift the motor or raise the motor?
Fred I'm confused. Do you mean the motor is heavy for you to lift and place on the transom? Or do you mean the motor is too heavy to raise on the transom bracket when your'e sailing? If the latter is the case then get a new bracket with gas or spring lifts that will handle the motor weight and save the money if the outboard runs well. Steve
