Hello. I got a good buy on a 6 year old Com-Pac 23D/MK IV sailboat and trailer (the "D" means the sailboat has an inboard Westerbeke 12D 2-cylinder diesel motor). I purchased the boat taking the word of the salesman and boat yard mechanic that the motor had just been de-winterized, "commissioned" and was in like new condition - plus it looks like it is in new condition. I towed the boat home and it sits in my driveway while I check things over and get it ready to sail. I want to run the motor. However, the Westerbeke owners manual and some friends all caution me not to even turn the motor over even for a second because a dry water pump impeller will self-destruct in a nano-second. One friend suggested disconnecting the raw water intake hose from the sea cock and lower a 5-gallon bucket of water down into the bilge and put the intake hose into the bucket and thus maybe be able to run the motor for a minute or two. My idea is to visit my local boat ramp one slow afternoon and not even launch the boat, but simply get it into the water deep enough to let the raw water intake have access to bay water. My question and concern is - how do I know that the water pump and impeller will get wet - have water in/around them? The boat has been sitting in my driveway and the raw water system is drained bone dry. I do not believe that simply sticking the raw water intake hose into a bucket of water or into bay water at the boat ramp will push water thru the rest of the hoses and connections and into the water pump. It seems to me, I still must run or turn the motor over for a few seconds - and thus turn the impeller while dry - to draw water into the dry system - thus destroying the impeller. I guess any new motor first put into operation would face this same problem. Or, any motor that had a water pump replaced or overhauled.
Any suggestions on how to force raw water into and thru the water pump before attempting to start the motor?
Thank you.
