2 cyc oil tank

[garagenc]

I have a 86 V-20 cuddy with a 200 hp mrec bluewater series motor, the plastic 2 gal oil tank is not permanently installed, where does everyone else have theirs sitting?

mines sitting in my shed, its been disconected, the only reason i didn't throw it away is they make a good jug for waste oil

Hey Spare

Aren't you worried about fouling the plugs? I hear those plugs are about $15.00 a piece. Does this model have trouble with the oiling system?

Mine was disconnected also. It's malfunction blew the motor once and I wasn't gonna let that happen again.

I dont have a Merc but ours is disconected too. They are sitting under the boat right now. The place where they were makes a great place to move the batteries! The main reason they are disconnected was because they kept overflowing the tanks.

this is mine (83 cuddy). it is located on the battery shelf between the stringers in the bilge. i had to put an access hatch in the angled part of the splashwell to get it down there. been there 14 years with no problems.

the optis use the expensive plugs, and $15 is for the cheap ones. Mercury oiling systems are not the best, they aren't the worse either, but after they get some age on them, I don't like to contiue to run them. The oil pump is driven by a plastic gear on the crankshaft. the plastic gear can fail and cause oiling problems. Ive also seen the clear plastic hose that feeds thr oil to and from the pump crack, it will pump the oil insode the cowl and never set the oil alarm till all the oil is gone, because the pump is still spining. Its not that hard to disconnect the system. the oil tank in my 79 was under teh hatch in the splash well. If you had to access the batteries or oil tank while in hte water, you can risk lettingwater into the bilge, especially if you are in rough water. i moved the batteries into the fish box area under the floor to allow access from inside the boat. http://www.wellcraftv20.com/community/showthread.php?t=5000 jeres teh link showing where I put them, haven't finished the job, still trying to finish the Glastron

I never ran oil tanks on my outboards, But when I got the Yamaha they all said it was the best!!
3 seasons that best Yamaha blew up when the oil pump stopped working with no alarm!

I am now back to OMC and there is no oil tank in site, nor will there ever be!!

[spareparts]

the yamaha has the best setup, but no alarm for oil flow. Even the best ain't but so good.

Not knocking Yamaha cause I loved the motor, and would get another in a second!!
More was just saying what you said, No mater what motor it is you are doomed sooner or later with these oil systems!

My oil tank is in the garage right next to my scrap pile. The 2.5 MERC's have a plastic 2 piece crank gear that drives the oil injection pump. These gears are very well known to fail if you bring the engine off idle before it's up to temp. The 3.0L MERCS have the same basic system that the YAMAHA's and SUZUKI's had. They were pretty reliable, but the 2.5's were not the best. MERCURY changed the platic gears out sometime around 99-00 for a bronze gear which helped out alot. Which 200 do you have? The 20o was availible in either a 2.5L or 3.0L. IIRC the 200HP BLUEWATER was a 3.0L, the OFFSHORE series was a 2.5L.
