Start at the end and read backwards for the cliff notes.

holy cow..... well i guess the question still stands. what to use in a 1992 4.3L that only gets used on a small lake pulling a tuber or just cruzin at 30mph??? this boat never goes out for more than 3 hours at a time... thanks for the information and i am still going through it at this time but would like to hear what others are using.
thanks

NAPA 15w-40 would be fine for your 4.3L

are you serious??? i am new to boating. thats kinda thick isnt it??? not questioning your knowledge about boats because i know nothing about them... y do you have to run such thick oil in the motor? thanks for your time guys on teaching a me a lil about boats

15w-40 is not too thick for your application. A straight grade 70 would.

Use the 15w-50 or a 20w50 your motor will be happy and thank you for it.

the 15w-40 is ideal becasue when the oil is cold, it will run like a 15w but when it gets hot, it will run like a straight 40. I am a believer in the blends. hope that helps.

If you think that sounds "thick," you should see what Mercury recommends. How's 25w-40 sound? If you go to any Mercury / Mercruiser dealer, that's what we'll sell you. Trust me, it works.

I'm running 15w-40 rotella t in my twin 350 setup. Works great never had any issues.

Go to Walmart pick u p some Mobil 1 synthetic you'll be just fine. 15w40 or something close...20w50 is too heavy of a oil for a 4.3L
