So I have two boats that never get run and I need some advice.
Boat 1 is a 33' bertram with twin gen5 454's carb'd. One motor is down due to bent valves so the boat is going nowhere soon. I currently have rotella 15w-40 in it but I'm not sure how often I should run it to keep the moisture out of the oil? It doesn't have pcv's, just hoses coming from the valve covers to the air cleaner on top of the carb. I can run a pcv to the base of the carb which I might do soon to get some vacuum action going.
So, since I never use this boat, how often should I start up the motor and how long should I let it run for? It's an inboard by the way. Should it be run in gear? At idle?
Ok so boat 2 is a 27' sea-ray. I put in an 8.2L volvo penta mpi back in 2000 and the motor has about 150 hours on it. I may take it out once a month, if that. Especially now that it's cold. This motor will also have rotella 15w-40 next time I run it to warm the oil.
This is a sterndrive hooked up to a mercruiser bravo 2 x diesel drive. So the same question, how often should I start it? How long? At idle, in gear, etc? This is a newer motor with a pcv, electric sensors, etc. Exact model is dpx415.
Both boats are behind my house and are tied up well, so I don't mind putting a little strain on the ropes to run them in gear. Also, both boats will not be winterized but will have bilge heaters going to keep them above freezing(just).
Thanks for the advice guys.
