Boat change 312 1986 Stinger
 

Hi from Finland !

Just change my previous boat bayliner 2450 to stinger 312.

This boat feels like driving in different planet when compare my previous bayliner..

This stinger has two 454 with stainlessmarine exhaust and through hull tubes.

One engine are merc magnum and the other is marinepower 330hp.
Both engines has edelbrock performer rpm intake manifolds.

How fast this kind machine schould move.

I get 48knots in gps. Props are 14,1/4" * 23"
magnum takes 4500rpm and marinepower 4100rpm

Schould i change props to 21" ?

Something solved..:angry-smiley-044:

other engine electric fuel pump fails. I change new pump
and now i get over 50 knots (60mph).

Are there anyone who has 312 ?

Every one who has 312, put your top speed and engines here.
I really want to know how much top speed can reach with different engine assemplies. :)

Might I also suggest a profile name change to suite your new (and much better) boat?

Be sure to post some pictures of your new boat too.

Mine's a 222 so the speed is not relevant.
