4.3 GM marine cam part number is suspiciously the same as the GM Silverado/S-10 truck cam
Not sure where you are getting your info.
Other than the core plugs, water pump and the head gaskets (early on) the 4.3 coming down the Tonawanda line didnt know if it was a truck motor, a forklift motor...
If you can call 24 grit ground fiberglass smooth
Post a picture. Usually when you think you have ground enough, there is more to do. Need to make sure your down to good glass and you are out about 8 to 10 inches past the stringers
A new 4 barrel carb and intake will set you back less than $1000
Watching auction sites and posting sites and you can find good, used for half that.
$1500 for a carb means you better get kissed, because you just got shafted
And what is the towing capacity of your SUV?
What you normally see is dry weight (no fluids), and if it's a boat with an outboard, the weight is without motor
Typical single axle trailer is 600-800#, typical tandem axle trailer is 1200#
@jimmbo I had an opportunity to tour Barr when working on the Verado CAC. They make castings for Edelbrock, Volvo, PCM and many more. Lots of design commonality across various brands
installing a carb spacer and increasing plenum volume increases low and midrange
BTW, Volvo Penta manifolds and Edelbrock manifolds both come out of the exact same casting boxes at Buddy Barr castings.
Not sure what your issue is with your motor, however I suspect tuning and potentially carb...
Other than making sure the HIN and paperwork match, you have a boat with an OMC stringer in it
Boat brand means nothing to trouble shooting and fixing your issue.
If you are looking for a manual, it doesn't exist other than the OMC factory manual
FWIW.... For pulling tubes, putting around, fishing, swimming, diving, golfing etc. I would get a tritoon with one or two big outboards and a front mounted swim ladder
First, get a new mechanic
Do the work yourself
Work with your local machine shop
Head job between $100 and $400
Full remanufactured long block between $1500 and $1800
New GM long block $3400
There is no sensor
You have a bad or multiple bad connections
Start by cleaning every connection from the battery to the helm and back
That is about 18 lug type connections, about 40 ring type connections and about 50 various other connections
Start googling 3-prong trailer wiring plugs.
If it was me, non insulated butt connectors and epoxy lined heat shrink tubing and I would be done in 5 minutes
i would be suspect of the head gasket
yes, you most likely fried the voltage regulator.
there are some 30 amp outdoor power equipment regulators I would be willing to try if I was in your shoes.
