Oil Type
I have twin 5.7 litre merc cruiser engines. Thunderbolt ignition. I bought the boat used and the former owner who had it for 18 years has always used 30W non-detergent oil on the engines. Mechanic recommendations are 25W40. Does anybody know if there would be any issues with switching to the 25W40 oil now?

Re: Oil Type
Ask Mercury in Fon du Lac on current thinking on weight.
That's your very best answer.
