One other option is an Orberdorfer. Much better pump.

Prestolite 51 amp that puts out 14 volts and a Facet original equip fuel pump in good shape. $75 and $50 or $100 for both. Alternator is about 5 yrs old with a nice machined pulley.

M 25 engine.....D 850 Kubota ?... started to blow a lot of grey smoke. Compr. test revealed 0 PSI on back cylinder with 425 on 2 front. Rear cylinder valve adjustment tight, adj valves, compr came up to 90 or so. Removed head. Found back cyl piston to be pock marked, looks like small craters on the moon, head also has some pock marks. Its almost looks like a piece of hardware went through this cylinder, but I am not sure. Also, when removing injectors, back one was only hand tight while others took a breaker bar to get loose. Back injector tip is also very sooty and oily, while front 2 are uniform dark carbon layer. Couple of questions; could a loose injector and tight valves cause some type of mis-fire/detonation that could cause this internal damage? And are real Kubota parts still around for this engine. At the least I need a new piston and some head work. Cylinder bore looks good with no ridge. In the Tech WIKI there is an old article about a guy in the Bay area doing a partial rebuild. The pictures of his rear piston looks a lot like mine. Appreciate any help.

Another potential issue; is the alternator putting out mucho amps due to battery or regulator issues. I remember discussions about how the single v belt gets overloaded as you go above 90 amps or so with the alternator installation.

Good point Ron.

A couple of guys in out club got their Hurth boxes rebuilt in the NY area for under $800. No problems since. Not fun to remove as the bell housing has to come off.

Thanks Ken! Should of known it would be in the wiki.

A friend with a 1999 C34 just swapped out yet another junk Sherwwod pump. He found that one of end tangs of the cam was cracked. The bushing is in place as per the SB. I wonder if this is an isolated problem. Local dealer is quoting pulling the engine and sending it to Hansen for repair.....crazy $. Has anyone done this repair? I know the timing cover has to come off. Universal wants something like $1200 for the cam, I assume the Kubota part is the same and much cheaper. What is the Kubota model # for a M35B?. Thanks.

Mainesail's site and this one discuss a K+N air filter element. Did it on my old C34 and now have it on the C400. Works great.

Main Message Board / 3 Blade Prop Question
« on: September 09, 2014, 06:15:55 AM »
I am looking to upgrade to a 3 bladed prop. Research on this site indicated a 9.5 or 10" by 15 is the way to go. I also understand I want a " sailor " prop. Are the props offered by Catalina Direct the proper types, or do I have to go through the Factory? !988 C34 M25XP engine. Thanks for all help and info on this site.

Probably your charging issue, but more importantly a potential safety issue. Take the alternator to your local automotive electric shop for repair.
