[C38] Maxprop setting

[Michael Norcross]

A few years back I had an issue with getting the revs up on the 3 blade classic maxprop, which was associated with black smoke when I pushed it. After several tries I ended up going down on the pitch, to believe it or not,  14 degrees according to the Maxprop manual calculations. When the exhaust riser finally fell apart I had the thought that the exhaust was compromising the output of the motor. With a new riser, the motor runs cleaner, but the boat is slow. Since I have the boat out of the water, I was going to reset the prop. Does anyone have a Maxprop and what settings are you using? i have the original Universal 5424 and a 2:1 ratio in the transmission.

I have replaced 3 fuel pumps in the six years I’ve owned Peregrine (I have no idea why so many) this last time we just finished a 12 hour delivery from Victoria and the next day when I started the engine at the dock, the pump failed within 1 minute.  Not wanting it to happen while cruising or at an inopportune time the following project.   I installed a second fuel pump, two valves and a switch for current.  Now with the turning of those two valves and a toggle of the switch the second fuel pump takes over.   I’m having a plaque made up that shows the valve and switch positions and plan to mount it just above the fuel filters.  Pretty sweet.
