Master Auto Mechanic seeks Marine Mech.

[Bellboy]

Hi gang, am a newbie here.....have been a professional auto mekanic for 25 years and am now getting into the marine scene and would like to meet up with any locals who might be willing to trade info and misc mechanical war stories.<br /><br />Located in the San Francisco area--anyone nearby wanna chew the fat? Am resurecting a '60 Bell Boy and want to repower it with a '75 Rude 115hp V4.<br /><br />It's a running engine, but I plan on doing some preventitive stuff before floating it....reseal, rering (if needed), water pump (or impeller), reeds, carb rebuilds, etc etc. <br /><br />I just hate the idea of going out with an unknown condition engine and possibly breaking down, ya know? TIA<br />-ANT<br />monarch_of_menace AT hotmail.com <br />(replace the " AT " with an "@)"

Re: Master Auto Mechanic seeks Marine Mech.

Well, you came to the right place, ANT. Welcome to iboats. Grab a beverage, Pull-up a chair, and join-in. There are a few really excellent Jonnyrude wrenches in residence here (not me tho).<br />If the compression is in spec, re-ringing is the least of these.<br /><br />Any motor that has sat for longer than a year, and all these preventive steps must be taken;<br /><br />Absolutely, impeller replacement (every 2 years whether it's bad or not).<br /><br />While you have the lower unit off, drain the lower unit. Follow the general instructions found at this link--- Lower Unit Inspection <br />The carbs will need going-thru for sure.<br />You will want to rebuild the fuel pump, as they don't handle today's fuels very well.<br /><br />Every skipper worthy of being on the water, has those concerns on his/her mind allways. Weather,other boaters, underwater hazards, and of course, the equipment under him.<br />Even if you took every precaution,(which you are well-advised to do), stuff happens out there all the time. Spend as much mooney on emergency equipment as you can possably spend.<br />VHF radio,EPIRB, Signal flares, Dual batteries, spare prop, spare plugs, a dash full of gauges, a Towboat US card, a stout bildge pump, a good set of waterproofed tools all come-in handy,when they come in handy.<br />I still have that bug in the back of my brain every time I leave the dock myself.<br />Just as in auto tweeklin, the shop manual is a must-have also.<br />I live in L.A. -- that's Lehigh Acres, Florida, so I'm glad we can at least discuss boats here .<br />Again, welcome to the best site for us skippers ever setup.

Thanks for the welcome 12Footer, this is a most friendly forum!<br /><br />I know exactly what you mean by being "over" prepared....I have many aircraft buddies and they are about the most anal of all mechanics--you can't blame them because if you have a problem with a plane you can't exactly pull over to the nearest cloud and fix it!<br /><br />One of the reasons I mentioned possibly changing out the rings was because the previous owner said that the engine was a little smokey....on automotive engines loose bearings can also cause this (loose valve guides too, but this being a 2 stroke, that doesn't apply).<br /><br />In case you or anyone is wondering why in the name of all that is unholy would loose bearings contribute to oil consumption I'll tell ya.....loose bearings will fling oil off their periphery which ends up getting sprayed onto the cylinder walls overwhelming the oil control ring's ability to wipe it off---in turn allowing it to get past them and into the combustion chamber. Woof!<br />-ANT

Re: Master Auto Mechanic seeks Marine Mech.

Always good to be careful. Before planning all the maintenance job etc. you should test run it to get your own idea about it. Being a 2-stroke it is different to car engines and 'smokey' could cover a completely normal situation. Afterall burning oil, especially when cold, tends to leave a little white smoke and it is no reason for replacing parts.

Re: Master Auto Mechanic seeks Marine Mech.

Then oil control ring distributes the oil. The oil scraper ring wipes it off.<br />Unusual excessive amounts of oil being slung is from excessive rod journal axial play rather then bearing play.<br />A healthy scraper ring and cylinder wall can deal with the oil being slung by the rod bearing journals. Worn rings and cylinders have an increased burden from excessive crankcase pressure overcomming the poor seal between the rings, cylinder and piston ring grooves.<br />An overfilled crankcase can duplicate this entire process. <br /><br />Welcome aboard.

Re: Master Auto Mechanic seeks Marine Mech.

Hi Skinnywater, yes, a healthy oil control ring *should* be able to handle that excess oil, but if your engine is exhibiting loose bearings then the overall condition is suspect.<br /><br />Solution: Pour some Slick 50 in it. <br /><br />No!!!!! Just kidding. About the only thing worse than that would be sand.<br /><br />Where in Calif do you hail from? I be up in Sam FranCrisco.<br />-ANT
