502??
 

What year 502,s do I have to be careful of?? With oil consumtion??? do the older 465 have valve problems???

Mine is a '94 HP465. Same as the HP 500's other than cam and intake. I never heard of any issues of oil consumption or valves. Not to say there isn't. Mine has never used a drop of oil either. The original cam was a bad choice. Not compatable with silent choice either.

I had a 2000 502Mag in my last boat. It burned about a quart of oil every 10 hours. In contrast, my 496's burn very little between oil changes every 25 - 30 hours.

my 1997 502 uses at about the same rate as the 2000 mentioned above. Varies depending on number of hours on oil change.

502 oil consumption
 

mine is a '95 new to water in '96

probably 10 hours to a quart - always has been that way. An old hot boat article confirmed some of the 502 mags - use oil. Merc manual calls for a quart every 6 to 10 hours.

Oil's cheap.

US1 what do you mean not compatible with silent choice?? And did you sell your boat?

My boat came with straight thru hull. I wanted silent choice. I talked with the Fountain factory and was told they had problems of reversion real bad, so they didn't put choice exhaust on it. I also contacted the Crane tech line for a second opinion. Was told same thing. Too much cam overlap or duration, I forget. Crane said they discontinued that cam as it was a dud. It even showed signs of reversion with the straight thru hulls. I just changed over to the Crane Hyd. roller cam when I installed the choice exhaust. Dry as a bone. And yes, boat sold just yesterday. Or at least they left a deposit are going to bank on Mon. But, until cash is in hand.....;) You know the drill.

Thanks for the info, Yea I know the drill, That is one sweet looking fountain you have. If I wasn,t married I would ----Well then again if I wasn,y married Id be waking up in the gutter thinking I was having a great time. What are you going to buy??

Thanks! A 32' Fountain has always been the initial plan, but lately been thinking of things like Cigarette. Just not sure. What are you considering that has the 465?

Same as above, 1996 502's, 1 quart every 10 hours each. It gets expensive if you put a lot of hours on them and use synthetic oils.....

Not trying to derail this thread but.....
US1,
We met last year on Monroe. I have the 28 Thunder. You should take a look at Todd's Best Revenge. It would be a great boat for you. Just a thought.

I found a Formula 271 with a 465 in it but the #,s don,t work

All BBC's use oil. It's something you learn to keep an eye on.

I have a 454 never use a drop original motor from 1988, But I have heard the 502,s burn some

oil
 

The low horse power 454s (many) don't use a drop. However, the high horse power 454s and 502 with forged pistons DO use some oil, which is a lot cheaper than parts.

Ok, what part of "Mine has never used a drop of oil" do you guys not understand? :) ;) And this is with a blower. sheesh. :D :D (Just yankin your chains)

Bob O...... wanna go looking at boats this weekend? ;)

boatfreak, hey dude, hows it going? Going to be back on Monroe this yr? We did considered an AT for a bit until we seen the tailpipes above the swim platform. Look like ankle scrappers.

peace out
