I just purchased a 2000 Ski Nautique with an upgraded 350 chevy motor and zero off. I was looking at the engine trying to find block drains and couldn't find any. On my 1989 2ohoh1 351 Ford there are four block drains. I ski all year so for winterization I drain the rather than use antifreeze. Anyone know if and where the block drains might be? I am away from the boat but will post some photos when I get back.

Hey Art. Nice upgrade. Looking forward to a pull behind it. Sorry we didn’t get together down here for a little bit of course action. I got out some, but not much due to some back issues that culminated in surgery about a month ago. But I will be as good as new next summer and we will get together here or there. ------------- _____________ “So, how was your weekend?” “Well, let me see…sun burn, stiff neck, screwed up back, assorted aches and pains….yup, my weekend was great, thanks for asking.” |

In the picture below, the brass fitting is screwed into the block drain. On the right side it's halfway between the front and back of the engine at the bottom of the block above the oil pan, a little ways in front of the starter like in the picture. Same place on the left side, halfway between the front and back 
Depending on what model you have, you might have plugs screwed in those holes or a knock sensor screwed in on one side and a plug in the other......or some variation on that , but whatever's in the holes, that's where the block drains are located.

or a knock sensor on both sides.. most of the three bolt DBW throttle bodies had two knock sensors in the block. the four bolt versions with the larger ecm only has one knock sensor and a brass plug on the other side of the block.. Reminder to not put any sealant on knock sensors or teff tape when you reinstall, there should be plenty patch lock on the threads for multiple winterizing.. ------------- Hobby Boats can be expensive when the hobbyist is limited on their own skill and expertise. 1993 Shamrock "fat" 20. 2008 Nautique 196 5.0 |

Thanks Keno and Jody, I will look for the plugs, I did see the knock sensors on one side. So it's ok to remove the knock sensor to drain the engine? Would a tee work so a petcock could be installed to drain the engine so the sensor wouldn't have to be removed each time? Larry sorry for the back problems but glad you are on the mend! I look forward to getting together in the summer but if you ever feel like coming out this winter grab a dry suit and come on up!

I use a 1/4 inch tee fitting like this......1/4 inch male NPT with 2 1/4 inch female NPT Then screw the knock sensor into the 90 degree hole and use a 1/4 NPT pipe plug (or the petcock you mentioned) at the end, That way you can stick something straight up the drain hole if the hole or fitting gets plugged with sediment, rust etc.  Sometimes a wye fitting is used there, but it's harder to stick something up to do some unplugging.

| I haven’t done much homework on this but I would hesitate on changing the mounting of a knock sensor if you intend for it to continue functioning correctly. It works by picking up engine vibration- pulling it away from the block on an additional structural member (y/extension/tee/etc) could disrupt its ability to detect knock or even falsely detect it, I would think. I know removing to drain the block is a pain, but might want to do a little more research, first. |

I did enough homework a handful of years ago to tell me it was worth a shot. It kinda went like this.....the PCM part number for a SBC knock sensor that I had (R020027) cross referenced to plenty of other companies like Mercruiser, Volvo Penta, Indmar, Crusader, Sierra. They all used the same GM supplied knock sensor in their SBC engines around late 90's into the 2000's, or in the case of Sierra sold one to replace all the part numbers from the OEM's.. Some screwed into the block, some screwed into a wye fitting with a drain plug on the other leg of the fitting. Same sensor screwed into that big hunk of metal block a little differently. Asked myself if I thought that the ECM's and knock sensor modules were calibrated differently for that little wye connection, said to myself "I doubt it" and gave it a try after doing some reading about knock sensor relocation kits for various engines and whether a new sensor was used or just the old one relocated.. I used a tee like mentioned above, instead of a wye. Nothing changed, engine ran fine. Did I do any highly scientific testing? Nope, just a little logical backyard hack thinking and testing. I'm sure it could be argued all day long about whether there's an effect, but that's for somebody else to do I guess we all have different comfort levels with certain things, so it's a do your own homework kind of thing.

OK dumb question, does anyone know what the up/down buttons on the key panel are for on my 2000 Ski Nautique? I looked in the manual and couldn't find any information as to their function.
