Did fluid changes on my '07 RZ2

[Timmy!]

I changed the oil, v-drive and transmission fluid on the boat this past weekend. For those of you that don't have the funds (or don't want to spend the $$$) on a fluid extractor, I would highly recommend this $15 pump from Penzoil. I took a 1/4" air compressor fitting and put it on the end of the oil drain line and hooked up this pump to it and sucked the pan dry in under 2 minutes (boat was on a hill with oil facing the drain):

I bought mine from O'reilly but I know Autozone and Advance both had them as well. It also worked great for the v-drive and transmission.

This is for the Marine Power 340hp 5.7L
5 quarts 40w oil
1 AC Delco PF1218 oil filter (Fram PH5 (or PF5?) works too but the Delco is a little shorter which made it easier to put on)
2 quarts ATF (1 in the trans, 1 in the vdrive)

While pulling the oil filter, I noticed that something looked funny about spark plug #7 so I pulled it and the porcelain was cracked on both sides so I decided to just replace all 8 plugs even though I am only at 190 hours or so on the engine. All of them were out of gap so not necessarily a bad thing.

8 AC Delco 41-993 platinum spark plugs ($6 each).
spark plug gap is .060

Happy Boating

Good Info Tim. The whole which oil type debate still confuses me! I keep reading/hearing conflicting reports. 15w40, 5W-30 and 30wt. Does anyone know what Marine Power suggests. I know in the past Tigé recommended 5W-30.

I just hit 400 hours and haven't replaced my spark plugs, now maybe a good time.

While looking in the MP owners manual for the spark plug gap, I came across the oil recommendations and they say "Marine Power does not recommend multi-viscosity oil..." and then it tells you want weight to use based on the temp you will be operating it. I said this in the other thread as well, if you are using 10w-40 or 15w or whatever, just make sure you let it warm up before you go out and run it wide open or above 3k rpm and you'll be fine IMO.

Does anyone know what Marine Power suggests.

I called MP when we bougtht our '04 and they suggested stright 40w

I talked to marine power last week and they recommended 40wt engine oil for my '07 20v. I also used that same pump ($12.00 @ pepboys). I ducked taped the drain hose from the oil pan to the suction hose on the pump and it worked great for the money

I have the same boat and motor and My owners manual calls for ac 41-932 with a gap of .035. Is there a advantage to using the plug you used?

[Timmy!]

That's weird. I didn't use the manual for the plugs, I just pulled one out and that's what it was.

[dom w. forte]

I would reccomend checking the plugs at about 400hrs , but if the electrode still looks good leave them alone, I currently have 1000hrs on originals, no power or fuel economy issues, these engines are designed for 100,000 miles tune ups, main thing to check is dist. cap and rotor, they corrode the terminals and over work the coil, and keep the flame arrestor clean.

Yah I think ill spend the few bucks and keep my boat maintaned. Not trying to set no reconds on how long I can go with out caring for my investment.

Great info Timmy

I downloaded the owners manual from the tige site and it is different than mine it says use the plug timmy used AC Delco 41-993 but sayed use a .035 gap. So I started poking around and on the valve cover it says .060 gap (same as timmy) so I pulled a plug and confirmed it is a 41-993 with around a .060 gap so my conclusion is that the owners manual is wrong on this application. Sorry for the confusion

[Timmy!]

Thanks for updating this with that info! Crazy that the manual says one thing and the valve cover says another. I couldn't remember where I found the info to be honest but I knew I got it from somewhere.
