Thanks guys for the advice. As the boat is currently running beatifully I'm reasonably comfortable that I'll get through the 10 days at Port Mac trouble free - but who can ever to be sure in boating !!!.
As precaution, I am (0r should I say mechanic brother in law )is putting new bearings on the trailor and helping me to give the boat and trailor a good going over. Given the previous owner gave me a new 4 ltrs container of Yammie brand motor oil, and based on Huey's suggestion I may as well give the boat a basic oil, filter and plug change. I'll leave the rest up to Huey in the new year.
Thanks again guys
Bill
