RPM Information: 5000-5500
Your engine's RPM range is important in choosing the right propeller for a given application. For example, if you look at your tachometer at top speed and it is not within the engine's RPM range then that is generally not good. You want your RPM's to be within the proper range while at wide open throttle (WOT). Be sure to do your testing under your normal boating conditions and with a good propeller (not bent, cracked, or excessively chipped).

I was able to spend a little time messing with it last night. It started right up without hardly any choke which is better than it has been in years so that's encouraging. As I was warming it up I noticed the amount of water coming from the site hole was a weak stream. This was way different than when I was running it on the muffs and much less than it use to have. I'm suspecting an overheat problem at this point. It might not be my entire issue but I have to get that fixed before I go any further. I suspect the guy I had work on it last year ran it without the muffs and fried the impeller. I'll replace that this weekend and report back.

Sorry for the novel but I should start with a little background. A couple years ago the top end seemed to be diminishing. The boat would start fine every time and run well enough it just wouldn't achieve the same RPMs as it used to. 2 Years ago it started to idle poorly and would stall when you put it in gear. If you throttled it up a hair and put it in gear it was fine once you got moving still having the problem at top end. So last spring I had the repair facility look at it when they pulled it out of storage. They rebuilt the carb and replaced the fuel filter but said after starting and running it a while it quit. They decided it was still fuel related as the compression and spark were good when it quit. This time they replaced the fuel line from tank to motor including primer bulb as well as the fuel pump. Bottom line is they kept the boat for the entire season never fixing it. I finally had to demand they return my boat as it was clear they were never going to get it right.
This year After trying to get several mobile repair services to come and look at it and not even returning my calls I decided to dive in. Based on the new gaskets and appearances it does look like the replaced the parts they said they did. I installed a new battery and new plugs and it fired right up. It ran on the water muffs for a while and then stalled. After cranking it a little bit and choking it the motor started back up and ran again for half an hour at 1/4 throttle on the muffs. I figured it was unlikely but maybe it had an air lock that they never cleared out and it was good. Dropped the boat in the water and it started right up. I backed away from the launch no problem and started across the lake at about 3/4 throttle, It seemed to have more top end then before and was running great until after about 200 yards it started losing power. I pulled back on the throttle and it would come back and I could throttle up again for short periods but it would start bogging down after a very short distance. I was able to take it down to just above idle and it ran OK and I was able to get it back to the dock. So at this point I'm hoping someone has experienced something similar and can provide some advice. [links]

Hi,
I have a 2001 Mercury 40HP 2 stroke serial number 0T475589 2 cylinder single carb. The motor is on a pontoon boat. here

OK, I was able to get an impeller today and installed it. I've not done one of these but I have done others without any issues. I watched a couple videos and went after it. Everything seemed exactly like the videos and it went together very well. It went all the way up into place without forcing it and I bolted it together. The water stream seems unchanged. Maybe it never was that strong off the muffs and I didn't notice. I suspect not though and I may have misaligned something going back together. I am adding a video of it draining when I lift the motor and it seems to be leaking from areas I don't remember it leaking from. But before I drop the housing again I figured I would post the video and get some opinions. I also attached a video of it running. The prime bulb seems soft and there is no change to engine RPM when I squeeze it.

IMHO your motor is flooding not starved - why? . new boat, so you haven't learned the quirks of starting your motor yet. wet plugs, only wet thing in the cylinder is petrol, or maybe oil if the motor is stuffed, but well stuffed to pump oil into the cylinders then, so I think it is wet with fuel. black plugs. flooding causes the carbon in your motor to loosen up and causes a residue of thick black wet shit on your plug - smell the plug as you take it out. petrol or oil? or carbon and petrol. Check the choke like was mentioned above and check your fuel pump and maybe your carb - needle and seat could be blocked open, and you are pumping heaps of fuel into your cylinder. on a 2 stroke, see if black fuel is running out of your exhaust, maybe down your motor leg---sure sign of way too much fuel. more

Seems nothing serious though, as when you replace the wet, flooded plugs, the motor starts.

Had a similar problem with my yamy 50. Definately sounds like a fuel obstruction. Mine turned out to be a load of bad fuel from the bottom of the tanks from the local servo that filled the filter and carby's with crap. Had the carbies cleaned and dropped and replaced the filter. Was amazed at the amount of crap that came out. Problem fixed after that. Cost me a lazy 300 to have the carbies cleaned though. Now I fill into jerries with a filter before filtering the fuel again as it goes into the boat. Bit of a pain but at least I now its clean fuel going in. Hope you get it sorted mate. [links]

I'm hoping that it was just a combination of small problems and my lack of knowledge that was the problem as I managed to have it running fine in the driveway yesterday. [links]
