Guys:
Just another update for this thread...
I've gone ahead and purchased a New Crate Vortec Block (5.7L).
Dropped at a New Local Recommended Marine Guy around 50km away... Will be getting installed next week.
I've purchased the
Electrical Fuel Pump Conversion Kit
New Intake Manifold
New...
Further to other messages... If I was to look at getting a 5.7L Vortec Block Swapped over...
What else would I need to complete the task?
I'm guessing
- Alloy Intake Manifold to Suit 8 Bolt Vortec Engine
- Some Sort of Carb Adaptor to Suit Intake on this Engine?
- Electric Fuel Pump & Oil...
Guys:
Just a bit of a further update... Determined my Alternator was caput.. so thought I'd try taking it on the water again today... Was happily plodding along at around 2000-2500rpm up to around 15-18kmh.
Anything further than that and the Engine sounded like it something was rattling around...
Guys:
I'm now looking into a Repower for this boat.
I've found a Vortec 5.7L which looks promising from local rebuilder.
I'm waiting for answers based on my question to him but thought I'd post here also..
I'm assuming with this Engine I'd need to
- Get Replacement Intake Manifold to suit...
Updates Guys:

Boat is running now ok out of the water.
I didn't realise myself the Button on Side of Throttle to allow you to choke/start at higher RPM... I've always tried...
I basically took photo's of what I had to begin with.. and re-installed with Bolts at around the same depth/levels etc..
I didn't do Valve Clearances etc as I just took the Heads Themselves off and re-install as they were.
I have another look today, fiddled a little with position of Disty Cap and I just never seem to be able to get enough of a combustion to actually crank and start properly... Just sort of puffs etc of it wanting too.. and a decent smell of petrol etc..
I don't believe it's Fuel/Spark related...
I think I'm unfortunately at the end of where I can take this thing..
There's a pretty significant coating of Milky Residue in the Rocker Covers now.. That wasn't there when I pulled the engine apart to redo Head Gasket etc.. I'm not sure if that can accrue purely from sitting in the Air a...
I think I may have worked out where my issue lies.
(Bear in mind it's 10pm at night in Melbourne, Australia)
Picture below show's my original Disty Cabling Setup when I got the Boat and it was running (before all the Overheating/Destroyed Riser Dramas etc).
Basically what this show's is that...
So I've got the timing on the Block listed as
18436572
As such I've been following the attached diagram when lining up the Spark Plug Leads etc..
Does this appear to be the correct process?
I have a vague recollection of the Rotor Cap/Spark Plug Leads previously being installed off centre per...
