    Oil sheen in water after start up

    I'm just learning VP drives. My new SX's trim motor/reservoir is mounted outside of the transom, in the water, on the starboard side tucked up between the drive and gimbal ring. ....another source of oil in water.

    "Fogging" new VP 4.3?

    Thanks for the info Muc. I've been to this site many times, but didn't scroll down far enough to see the free manual. ..also need to poke the dealer....again. I now have a copy of the manual. I think I understand why fogging won't work. High pressure direct fuel injection needs oil in the fuel...

    "Fogging" new VP 4.3?

    I checked the online copy of this manual. P. 90 doesn't address fogging. It does describe the two cycle oil process. "During storage the engine’s internal components must be protected from corrosion. This is done by introducing a Fuel Storage Mixture in to the engine. Fuel treatment and...

    "Fogging" new VP 4.3?

    ...hmm. OP here. My manual is back at our river place. I'll check p.90. Apparently I missed this.

    Convert siphon feed 'paint cup' spray gun to pressure feed?

    I'll be applying a lot of drywall primer and finish paint at our river house project. Enough that I will break out my old Sears pressure pot spray system. The original gun is getting iffy and I'm wondering if I can convert my Campbell Hausfield siphon gun to the pressure feed hose. It would seem...

    "Fogging" new VP 4.3?

    Above threads say to not fog. My owners manual said to put premix two cycle in the tank and run the engine. Others above said to drain the fuel filter and fill it with a rich premix ratio. I started to do this yesterday, but couldn't get a band filter wrench on the filter. Very little clearance...

    Buying a automotive engine to replace my mercruiser, need opinions

    All of this engine discussion is great learning, but a mile over my head. My input is while you have the engine out is a great opportunity to update hard to get at parts. Particularly the flywheel engine coupler and front and rear engine mounts. Especially if these are original. Transom...

    "Fogging" new VP 4.3?

    Also thanks. Goal is to get the 2 stroke oil in the engine and pink antifreeze into the sea water side of the closed cooling system. ....at the same time. First winter learning curve.

    "Fogging" new VP 4.3?

    Thanks much! This will work. ...I've got plenty of 50:1 made up for my Husqy yard tools. ..recon that mix should be good.

    "Fogging" new VP 4.3?

    I could access the spark plugs fairly easily on my Merc 4.3, and occasionally gave each cyl a shot through the hole, and crank it with the dead man switch tripped. One side of the new engine is accessible. Not sure about the starboard side. ...could take more excavation than I want to do.

    "Fogging" new VP 4.3?

    My owners manual says to mix two stoke engine oil into my boat's fuel and run it through to get the necessary corrosion protection over winter lay up. With my previous Merc carbed 4.3 I simply sprayed fogging oil into the carb. My VP 4.3 is high tech with high pressure direct injection, O2...

    Chris, the boat came with a VP alum 14.3 x 21. It pegged at 5800 rpm. I suspect it was rev limited. Slip was 17% WOT. I'll recheck slip at 3500-4000 rpm with the 21P which is where I spend most of the time. WOT is interesting, but scares the wife.

    VP SX 1.91. (Please don't hate me. The VP 4.3 has too many advantages over the Merc 4.5)

    Update: I purchased a Solas HR Titan 3 14.25" x 22P here at iBoats. I think I'm as close to the sweet spot as I'll get. WOT rpm = 5500 vs 5400-5800 spec. GPS speed = 55 mph. Slip = 8% Per @achris "The prop maketh the boat."

    Scan tool for new VP 4.3?

    Thanks, I recall past forum posts and discussions about Diacom vs Techmate. It seemed the trade off was convenience with the Techmate vs. less convenience but more capability with the laptop based Diacom. My post warranty objective is diagnosing engine problems, and resolving with DIY repairs.

    Scan tool for new VP 4.3?

    Thanks. I assumed I need a Rinda, but I'm unsure which model. The link below looks close, but I'd like to know which model others are using. I recall @achris once posted that he used his to reset a low oil pressure fault after changing his upside down Merc 4.3 filter and loosing prime. I'd like...

    Scan tool for new VP 4.3?

    I love our new VP 4.3. With their five year warranty I shouldn't be worrying about diagnostics and repair...yet. But I'm a DIY freak and a control freak, and I want the ability to know the cause of potential, or real trouble, as well as monitor things. Then I can deal with it myself if it's...

    Agree. Getting the correct SS prop dialed in can be pricey if I don't nail it the first try. Diameter and pitch decisions still have me wringing my hands. The only thing that made sense with my 21P=>23P experiment was a 500 rpm decrease in WOT rpm.

    Thanks I know SS would improve performance. I've got a hunch my 250 hp is overpowering and flexing the aluminum blades. The SS price doesn't scare me off. But we boat in the hazardous, trashy upper Mississippi river, and every bent prop shaft I've had came from a SS prop impact. ...aluminum...
