Will a 9.8 kicker motor get a CD 22 cruiser on a plane?

Well it's been a long wait but my 2005 CD 22 cruiser is do to arrive by next week.

Thanks to all the great write ups on the c-brat site I have ordered a few things a head of time.

I used to spend a week or more on my sailboat so I know what equipment it takes to get by for a time.

I ordered and received a 9.8 Nissan branded Tohatsu kicker motor. I was wondering if this motor would get the CD 22 up on a plane and hold it there.

I plan on doing some long distance travel and won't be in a hurry.
With the price of gas I wouldn't mind going slower and save the 90hp Yamaha for when I need it.

My 3 cylinder Yanmar diesel used to burn 1/2 gallon an hour on my sailboat. I was perfectly happy to make 5-6 Knots while traveling in the inter coastal waterway on long trips. After all it's the journey not the destination.

Thanks,
Rich
 
As Jim said, no. As I'll say - not even close. I don't know the exact horses that you'll need but my guess is it will take closer to 45 or 50 to get on plane. I couldn't plane my 22 using a single 40hp on a twin 40 setup.
 
That sounds just fine for running sack tides and with the current. If I need to make some time or running against the current I will crank up the 90 Yamaha and put it on a plane and run 14 to 17 knots.

With the help of this forum I have also ordered some goodies to make single handed running easier.

I have a EZ- Steer steering link to install to connect the kicker to the main as well as the throttle server control trolling pro 2 for the kicker.

Thanks for the information.

Great site the c-brats is.
 
I'll tell you that our Tohatsu 9.8 w/ the standard 3 blade prop (not the hi-thrust prop) pushed our 25 at 5 knots without any wind or current. Just completed the final break-in last week so I know the number is accurate. It fluctuated between 4.9 and 5.1 knots at WOT.
 
We have the 8hp Nissan, which is the same motor you have, just tuned for 8 vice 9.8. It will push the boat 6 or 7 mph wide open. Tilting up the 80 Yami doesn't seem to make any difference.

Enjoy the new boat!

On the same topic, I have wondered what size engine would be needed to plane an average 22 Cruiser if the engine was propped to be a single (vs. one of a pair of twins). I would have thought even 30-40 hp would do it, but that's just me guessing and I certainly don't know.

Back when some of the 22's were regularly sold with a single 50hp -- could those boats get up on plane? If not, then I have to wonder why they didn't just get something like a 9.9 high thrust - if they were only going to be operating at hull speed, 50 hp seems like kind of a waste.

I can see that 75-90hp is good for moving on out, but for planing along at, say, 10-12 knots, wouldn't a 40 or 50 do it if propped for working alone? Would a 30 or 40 do it?

I've just been thinking about this lately, so couldn't resist asking since it sort of came up in this thread.

Sunbeam, here's a thread that'll help.

The search box is very helpful. Found that with <22 AND plane AND HP>

I agree - I search a lot on this forum (and others) and it's a very useful tool. There's lots of good info to be found. I read the thread you linked to, and while it confirms one half of my thoughts (you can't effectively plane a C-Dory on a "half twin" propped engine of 40-50 hp), and it does touch on what may happen with a similar engine and a correct "single" prop, I didn't notice anyone piping in with has run a smaller single (smaller in this case being 40-60 hp). On the other hand, it may be getting too tangential to this thread, since the OP already has a 9 hp Tohatsu now.

I debated my initial reply (because... too off-topic?), but since people had mentioned not being able to plane on even a 40 hp, it had sort of been started, (those folks were using one of a set of twins vs. an engine propped as a single) and so I hopped in too. I guess the intersection of these thoughts is where my head was yesterday (coincidentally), in thinking about what the smallest (comfortably) practical engine would be if one wanted a light-sterned boat, and wanted to plane, but wasn't concerned about "high speed." In other words, a boat that would plane at a low speed and cruise at 12 knots comfortably, and maybe max out at 16-18+ knots or so. (I could see really liking that, and had taken a gander yesterday at the specs of the Honda 60 and the Yamaha 70 - those are nice, light engines at just over 250#. I found myself wondering how that and a Honda 2 for a dinghy/kicker would make the boat handle. Maybe the 70 would actually have a higher top speed than 18 knots, too.)

So when this almost came up in this thread, I was too tempted to pipe in! OP: Sorry if I got off on too much of a tangent :oops: And congrats on your new boat - let the fun begin! :thup
 
PS: The thread linked here has some interesting info, in case anyone would like to read more. There are some posts by people who have tried to plane on one 40 hp propped as a set of twins; but there are also posts by people who have had one "smaller" (<75hp) engine, which is where my head was.

I have a perfectly good, very-low-hours set of Yamaha F80/Honda 8D on my boat, but... I still think about options :D That "new" Yahama 70 has piqued my interest with a weight of only 257#. It would be interesting to find out how the boat would feel and handle with a more "original" amount of weight/horsepower on the transom. That engine and something like a Honda 2 on the transom would still be only ~285#. Pretty light (right now I'm sitting at 369# +108# =477# so that would be around 200# off the very back of the transom). I'll start a new thread if I decide to try it :D

Thanks for the reminder about that thread, Digger! I'd love to try one of those Yamaha 70's on my 22 :thup I even think my gauges and controls would probably work with it. Food for thought.
