| Post subject: | Water Pump in XDP drive? |
Hi all, I have a 2006 vista 258 with a 5.7OSXi & XDP (fresh water cooled). I am getting ready to winterize the motor/drive soon. From what I can see, It looks like the ONLY raw water pump is on the motor. Is there a water pump in the outdrive? When the boat is Pulled out of the water can I just run the motor on the flush port then put antifreeze in throught the flush port then drain the block? Am I missing something? If not that sound easy. Oh yeah I'm also going to: change engine oil & filter change drive oil winterize water system fog motor change fuel filter remove batterys coat motor with wd40 If any one can add to the list please let me know. Thanks Mark W |

Looks okay. I would remove fogging the engine and the WD-40 spray down from your list. No need to fog a fuel injected engine. |

Mark, There is no water pump in the XDP drive. To avoid any confusion, when you write "fresh water cooled" do you mean that the engine has a heat exchanger, or that it is directly cooled by you running it in fresh (= "raw") water? Very often, when people indicate an engine is "fresh water cooled", they mean it has closed cooling. If it does have a heat exchanger, the engine and inlet manifold are protected by an antifreeze mix, it is only the exhaust manifolds and risers that are not; in which case, it would only be the exhaust manifold plugs that need removing. Plus the anode in the heat exchanger needs checking/ replacing if more than 30% worn. If it is a raw water cooled engine, as well as what you have indicated you'd need to drain the manifolds/ risers, plus the owners manual indicates the coolant hose to the fuel pump module should be removed, to allow it to drain. It's not clear if this is also the case on a closed cooling engine; I imagine it would be as that must get cooled by raw water rather than the hot antifreeze mix !. Also, there are 3 anodes on the XDP drive that need checking/ replacing if more than 30% worn.. After 3 years use, if it's still the original one the impellor in the raw water pump should be changed as a precaution. If the old one looks OK, keep it and the old "O" ring as spares on the boat. WD40 tends to make things sticky and attract dirt; if you really want to spray something on the engine/ wiring, something like Boeshield T-9 is better as it leaves a non greasy film. Graham |

It is, I've seen in on E-bay, but if you source it irom the Ebay UK you'd pay about £20 an aerosol from a marine seller plus P&P! It's about 12$ in the US, about £8! There is a seller in the US on Ebay who will send it abroad for about $5 or 6. I bought mine in Florida the last time I was there! Maybe there's an aircraft maintenence company at Manchester airport that have it cheaper; it was designed by Boeing apparently! Graham |

Thanks guys.....Yes it has a heat exchanger. I won't use the the wd-40. I will get Boeshield T-9. I got a new impeller and will replace that in the spring. I shouldn't fog the motor? Here in NJ thay(the marina's) fog everything. I had 4 strok outboards and I didn't fog them.....so it make sense.  Should I take the outdrive off for the winter? How do you take it off? I don't see any bolts that look like it would take the drive off. Thanks I love this sight!!! |

Presumably like the DPS, the XDP should have the UJs. gimbal bearing, alignment checked yearly; the only way to do that properly is to remove it, plus it allows a thorough inspection of the bellows, which are prone to failure on the XDP from what I can gather. Graham |

It's best to follow the procedure in the manual as far as fogging goes...I always fog my old carb motor...but the newer FI motors require a different procedure...if you have closed cooling it's much easier to winterize... I recommend always checking the bellows for water and the drive oil for water...these things if neglected will cost thousands and the fixes are not that expensive... One thing that should be kept in mind is that any sterndrive boat is by nature very maintenance intensive...yes the engine itself is simpler than an outboard but everything else is more complex and in need of frequent maintenance...we are spoiled by modern cars that need little maintenance... |

Thanks Graham BTW if you can get Corrosion X or Fluid Film over there they would be just as good as Boeshield.... I used the Corrosion X HD (much thicker fluid than any of the above) on my trailer springs...ubolts...etc and that stuff really hangs in there...but too messy and drippy to spray on the engine... The most important thing to spray...which you can't really see...is the whole bottom surface of the oil pan...these are just painted steel so the pan and timing chain cover do rust through if there is water always in the bilge...I sprayed em good a number of times...... |
