22 Cruiser prop options

[ssilver]

Our 22 Cruiser is generally loaded on the moderate side. 2 adults midsize dog, weekend supplies. Boat has a newer 90 Suzuki alum Michigan wheel vortex 14" x 15 pitch. That prop works real well but now has a ding on one blade. I carry a spare Michigan wheel vortex 13" x 19 pitch. Just curious if anyone has any real world experience w/ that setup? The motor was originally mounted on a 17 whaler w/ a SS 14x20 that worked ok w/ a light load, we bought the 13" x 19 pitch for rough water and heavy loaded trips. Just curious what to expect using that on the C-Dory. We do have trim tabs and the permatrim. So essentially dropping an inch in cup and adding 4 in pitch.

I was seeing max RPM 6300 w/ the 14” x 15 @ 30-33 mph depending on load and current.

I just happen to have the 13” x 19 and was curious if anyone else had used it. I want to get out and do some fishing the striped bass are running and plan on dropping it in marina in about a week or so. Early in the season the river is full of debris so if I was to ding up another prop I just assume it be one I already have. I do not have any long range trips planned just a few miles north and south on the river.

Max RPM range is 5300-6300 sounds like the 13x19 should be between 6000-6200. I get I am not comparing apples to apples w/ a 1000lb skiff vs the C-Dory just sharing why I have a bunch of extra props. I also played w/ outboard height with the Whaler as it was pretty convenient sitting on a trailer in the driveway when not in use.

Spot on the aluminum ones are cheap I paid around $125 for them compared to around $500 for the stainless one I have. If it turns out the 14”x15 is that much better I will certainly order a new one before any long range trips.

Thanks for your input Bob much appreciated.

If you can turn up the 6,000 with either prop, you are on the money. It may be that one is a bit more efficient. The Speed is about what you would also expect with the correct prop.

With your 'moderate loading', you would be better off with twin 50s vs single 90 hp.

Consider the prop area difference; 2 50s, with a 11.6" dia prop, has 845.5 sq in
of prop pushing the boat.

A single 90, with a 13.5" dia prop, has 572.5 sq in of prop push; a difference of
just under 50% more 'push' area (surface area of propellers) with the twins.

This may not help your current situation already having a single engine, but maybe
for others who are trying to solve the old dilemma: one engine or two.

Aye.

OH OH, This topic line is going to go no where.
Except, downhill into the swirling water thing.

HAHA san juanderer I will see the results soon enough I was thinking somebody might have a DF90 w/ the a 13” prop to cure my curiosity pre launch. I was more than satisfied w/ the results of the 14”x 15 and will not hesitate to get a new one.

As far as two outboards, if I was starting from a clean slate I would have defiantly opted for two forty or fifty horse outboards. Mostly for redundancy when going off shore.

I purchased the 90 for my Boston whaler that I had owned for over 20 years with the intention of keeping them together. Than we decided we wanted to something we could overnight on and started looking at boston whaler, parkers, Steiger crafts basically pilot house looking boats. Just browsing boat ads one day I found a 22 cruiser that had no outboard and really liked the look of the boat. After a little research I discovered a 90 would be perfect. I was thinking I could just put the new Suzuki on there and it would be perfect. I reached out to the guy and almost feel over hearing it sold a few days after it was listed. I started looking for another and kept reading about them and ran across this site and lurked for a while. The more I read about C-Dory I just had to have one. I found the one we ended up w/ and bought it. She had a perfectly functioning 2004 Honda 90 w/ around 800 hours. I bought the boat w/ the intention of putting the 2004 on my old whaler and 2020 Suzuki on the C-Dory. This summer we do not have any offshore trips planned but maybe next year I will pick up a kicker for piece of mind. I cannot justify getting twins at this point. I am thinking about our next boat. Who knows I am open looking at 36’ trawlers or maybe a Ranger or who knows maybe just keep the C-Dory. I am getting closer to a retirement from my current civil service position and leaning towards becoming some sort of snowbird. We will figure it out.

Agreed: Prop thrust a more appropriate term what I used above (prop 'push area'
most likely due to a momentary cerebral flatus while typing... thinking of prop
surface area). It's no excuse. My bad.

It remains my understanding that bigger prop surface area, and thrust, is helpful
with heavier loads - coming out of the hole and onto plane as well as at moderate
cruise speed pushing the heavier load.

So, if I were to get a CD 22 I knew was going to be loaded to the gunnels as the
norm, I would look into the engine(s)/propeller(s) combo giving the most thrust
for my set up.

Aye.

I have a Turning Point 21431930 - 4 blade 13.9 x 19 that I tried on my CD22 Suzuki 90. I liked this prop at first but when I loaded up and went on a trip I found it was too much. I switched to a 3 blade 13.9 x 17 that works better for my boat.

Don't know what shipping would cost, but it's like new and I don't expect to use it. Let me know if interested.

Thanks Steve, I bet the 4 blade would be a bit much for my setup as well. Thanks Sean

[san juanderer]

SeaSpray,
How many rpm could you get out of the 19 pitch loaded ?
And the 17 pitch ?
Was this the model with the two different blade configurations?
thanks

[SeaSpray]

Sorry I don't remember the RPM numbers with he props. It has been over a year ago that I last ran that prop. The 19 prop is the one that needs the hub insert to fit the different motors.
