mercruiser 470 replacement?

[surchin]

what is advantage of a "bobtail" verses a complete motor? 4700 on sale complete is good. would i need to replace mount locations though? i have rebuilt the engine mount stringers a few years ago.

I do not think a new long block that is bare is a good option, all the working parts that attach from my old motor are pretty much 1978 orig or ebayed and the labor costs to remove and rebuild it would be more than a new motor. I do not have knowledge time or space to do it so I'm paying a shop the labor $100 hr. i can't see putting a 30 year old parts, starter, on a new motor as a good option.

RED FLAG!!!!
"Rebuilt engine mount stringers"
To do that is a full on tear down
Remove the cap, replace stringers (full length of boat) replace floor....
If you had stringer problems and did any less than that you can forget the motor and start boat shopping.

alright smoke yes def some orange flags flying out here, i just know what i have had to do to this old motor when i got this boat on the cheap and i would like to avoid going through that again trying to buy another old boat cheap.

where so you find an old boat in good condition anyway.

i don't know, i guess i will just use my kayak more.

Ur talkin about spending 10k.... That's not cheap...
10k plus whatever you can get out of your current boat should net you a decent water ready boat.

Surchin ...I also run a 78 470 that fortunately runs great. Recently picked up a 3.7LX 190hp fresh water low time engine for spare for 300 bucks...just sayin. If your are not in a hurry they are out there.

tw ya i guess thats another way to go - just keep shopping for one but man id hate to go through all that and buy a dog. There is nothing in my area and the pics i have seen of these do not seem worth the effort to purchase and ship one but i am open to any leads if you have any from your effort to get one.

Has anyone actually run a 3.0 and is it actually too little HP to push the boat?

A buddy of mine had one in a 17' bow rider .... It did great but that boat had less dead rise and less weight... It could plane a v20 but it would be a dog... Especially loaded heavy in big water.
