I am looking at a used 22 Cruiser with 2 Honda 40s.
Question: Top speed is 20 Kts and seems a little doggy @ 35k rpm.
And, it will not get to "on top of the water" plane with a single 40.
Is that performance to be expected? |

You should be getting in the mid to high 20's with twin Honda 40's. The wide open throttle should be in the 5,500 to 6,000 RPM (very minimum would be 5,000 RPM.
With a single of the 40's, you may not be able to plane, depending on the weight in the boat, condition of the bottom etc.
It does take some trimming to get the boats to WOT at max RPM--start up with the bow trimmed down, and then as RPM goes up, and the boat is on a plane, trim the engine back, and up--until MAX RPM, without cavitation or proposing.
There could be a number of issues limiting the engines, from bad spark plugs to carburetors which need cleaning--you should have the engine checked by a good mechanic before giving up on the boat. _________________ Bob Austin

Maybe. It depends on the load in the boat and what props are on the OB's.
35K seems like it should be at a decent cruising speed, certainly not Wide Open Throttle (WOT). I would wonder what that is?
Not planing on a single? Again, depends on props, load, and water surface conditions.

When we bought a cd cruiser22 it had a 50 hp honda on it and it planed off at 10 mph and top speed was 16mph with 3 big guys on board .So the 40 honda should plane it off might have to change pitch on prop Then re pitch both engines props and you will have a better hole shot and loose a little a top end speed
Also put doel fins or permatrim on both engines and you can use that instead of trim tabs
make sure compression is good and the bottom of boat is clean that could be the problem
We lost 6 mph with a crusty bottom it needed a good clean and paint job picked 6 mph 28to 34 mph with a cc-23 with a 115 merc ct _________________ retired 8/08 from UAL, still working pt tm

We had twin Honda 40s on our first boat. It would not plane on a single motor, but would max out around 7 knots if I remember correctly. WOT should be close to 6k rpm if set up correctly, and top speed was mid to upper 20s depending on how it was loaded. _________________ 2007 22 cruiser sold 10/2021

Thanks for the prompt responses.
It has become apparent the motors may not have been winterized, then set in a garage for 4 years. I'm thinking ethanol was involved ... in the fuel, of course.
The carbs are being cleaned, so we'll see if that helps.
Should I walk away, look for new power from the get go? $$
Any bets on a dramatic response? |

The jets on those carbs are microscopic so it wouldn't surprise me it will run fine after they've been cleaned. That's a desirable setup so I wouldn't necessarily walk away if you like the boat otherwise. I've had both twin Hondas and a single on the 22, and both have their advantages.
The newer fuel injected motors are more forgiving with old fuel. They can still have issues if left sitting for a long time, but its less common. |

Any of the used boats (and even new) are going to have trade offs. I would want to know how many hours the engines have one them. (Many make the point that hours are not as important, as the way the engines were rung and cared for.)
In this case, you know that the engines were not cared for--not winterized, and probably the carbs were not drained when put up. (We do that if it is going to be a month before the boat is run again.)
I would not rule this boat out yet--let them check out the engine and clean the carbs...then re-sea trial. |
