Gentlemen,

I have a '97 -16' classic 4.3L and 2 bbl. carb.. How can I tell what my "propshaft" h.p. is ?? I have searched the net and have seen this 2 bbl. engine rated at both 190 and 220 propshaft h.p.. with no explanation as to what the engine differences are. Can any of you "Donzi Guru's" shed any light ??? Thanx and a HAPPY NEW YEAR to you all !!!!!

"If you're behind me -------blah, blah, blah !!!!!!!!

Heads will be coming off and so will the gloves!

The wife is starting to want a boat of her own. She is liking an X-18 project boat. Hmmm!

You need to find a Happy Place to hang out. Go to your shop! My in-laws like to come hang out for a good while also. I am very glad that they are self entertaining! Clark Griswold did some really good stuff to my yard.

4.3, is 190hp 220 is q dream for a stocker, still trying to find the trailer boat article on that hop up. My Mother in law is great she cooks cleans and keeps the wife entertained and sticks up for me. when my brother comes down he and his wife help out for a boat ride, he's a boat freak too, mostly big sail rigs. Guess I'm lucky .

Dont get me wrong....they are good people just in moderation....I spent last wekend with my inlaws at there house for Christmas....thought I was threw with it and then they show up yesterday after noon and are staying tonight as well....GEEZ give me a break I need to decompress and gather my thoughts in my own space before returning to work in the morning.


I love them but they take up tons of space!



I need a boat ride in a big way!

Done now.....Happy new year.

In 1997 according to Mercruiser there were 2 hp ratings for the 4.3L.

4.3LX Gen+/190hp, this one is a 2b, I had this motor.
4.3LXH Gen+/205hp, this one is probably the 4b.
