Honda BF45 on 440 Hurricane problems
I've taken my new to me 440 Hurricane out a few times now. I've been trying to figure out the right prop to use on it. It came with a 11x13 stainless steel prop that gave me 47kph at 6300rpm with WOT. It also happens that I spun the prop bushing on my last outing so I'll need to have that fixed. My new prop is a Solas 11x15, this unit give me 47kph at 5200rpm with WOT. I'm guessing that this means I need a 11x14 or should I just stick with one of the props I have?
Another issue I have is that the motor tends to stall when I try to accelerate, idles fine, but when I try to accelerate it dies. This issue seems to be getting worse, to begin with it would not die if I opened the throttle up slowly but it would die if I opened it quickly. Now it dies about 80% of the time when I open it up fast or slow. If I can get it to open up it runs at full power with no problems. When I stop it will still accelerate ok if I do it right away. If I troll or shut the motor of for a short while the problem comes back. It seems like if a pump the hell out of the fuel bulb while slowly opening the throttle it helps a bit and gets it going but the bulb is firm, not soft. Any ideas on what I should look at? Perhaps I should add the water is quite cold here, there is still ice floating about so I'd guess the water temp is a couple of degrees C.
