Mako 22cc

[mastcaptjim]

I have rebuilt a 1972 22'CC mako from the bottom up. It is powered by a 225hp Johnson. The transom has been reinforced and the boat does a true 48mph. But the motor is gettinh old and I am thinking about repowering. Anybody out there have a similar boat. I am looking at a 150hp E-TEC. Think it is enough motor?

You won't do 48mph, and it'll be a dog gettin up. If you're looking at saving fuel by downsizing, I'd look at the 200's or maybe a 175. I really think that 150 is gonna be too light for a 22' mako.

Those old Makos are Great Hulls!

I'm sure I'm not the only one to say that...

I'm sure she did 48mph in her time. With new power (correct me if I am wrong) you won't need a 225 because of how they rate them now.

I always see Ed's in VA and Alvins selling motors cheap! Those Susuki motors are REAL NICE too. Won the JD Power award last year.

e-Tec's are so dam nice, but you will still want a 200. You always need as much power as possible, even if you don't use it everytime out there will be occasions you want all the power you can get.

My 23 Parker Sou'Wester planes in 3 boat legnths and moves 37+knots (conditions permitting) with a 2002 Merc 150 carb'd engine. Parker says the hull wieghed 2300# dry with no motor when built. Simple is good. Be honest with yourself...how often can you run 48mph in the DE Bay or open ocean, and do you want to pay for the fuel to do it? I'm getting 3 or so statute mpg at 3500 to 3800 rpm cruise at 25 to 27 knots (conditions permitting). The smaller powerplant also costs less to acquire. Look round in February or so for new in box previous model year engines with new warranty. You should be able to buy the engine INSTALLED with new wiring harness, controls, cables for about 30% less than current model year engine alone.

I used to subscribe to the 80% of max rated power school of thought, but that was when fuel was a buck a gallon.

my 97 merc 2 stroke doesnt come close to pushing my 20 foot proline 28-30mph at 3600 rpm, to get that speed I'm around 4400-4600. 42 mph in a 23 footer with a 150 seems high to me, maybe theres just a big difference in the parker hull vs the proline hull. ;D
If it were me, I would go with the max rated for the hull in both HP and weight. You may have to sacrifice some HP to get the weight and balance of the 4 stroke right, but IMO thats probably worth it. May be as simple as downsizing from a 225 to a 200. The thing about power is that you may never need it, but all it takes is one time without it..........

I would ask this question over on thehullltruth.com and see what kind of responses you get.

My 20 ft Angler DC did 43 fully loaded [ 85 gal of gas and gear for family of 4]with a 150 johnson both were a 2000

My boat is basically the same as your old one BH, and I top out at like 35 on good day lightly loaded flat ass water. Sounds like I need to get it in for a tune up. Could be a prop issue too I guess

Had the same boat in the family growing up with a 140 Johnson on it and it was under-powered at all the wrong times. I would also recommend the 175 or 200 for that boat, especially if you run through the inlets around here. It planed nice, rode well, and had gone 40m offshore.
My current 21WA with a 150 tops out at 41 under optimum conditions but rarely do I need WOT but I also think I should have gone at least 175, maybe 200 for that. There are times loaded getting on plane or facing an opposing tide through IRI or OCMD inlet that I wish I had paid for the extra 25 or 50 horses.

Note that I stated "under conditions." I think propping makes a huge difference on both speed and efficiency, and it's easy to get bad advice on props. I referred to the Merc web site prop selection tool and thier prop recommendation was dead on and identical to the dealer who sold me the engine.

Anyone here is welcome to a ride on my boat. I have traversed IRI on some pretty snotty days as well as DE bay in basically unfishable conditions. Part of the difference you note is due to hull form. This 24 year old Parker has very deep V at the bow and relatively little deadrise at the transom unlike some other boats. It also does not have or need trim tabs. Many newer hull forms are rather bulbous at the bow with deeper deadrise aft. In other words my boat is esentially a commercial hull adapted for sport, and was not designed for speed but for efficiency in nuts conditions. The 150 I put on 3 years ago performs at least as well as the '89- 175 Black Max it replaced. The boat is rated for a 250, which IMO is like strapping a jet engine on a piece of plywwood.
