Re: Unusual Clinker Build- 'The Anyhow'

Postby guilty338 » Sun Mar 12, 2017 8:08 pm

A bit more work over the weekend.

- Routed and connected teleflex cables for accelerator and reverse bucket
- Bolted on carby, starter, alternator, dizzy and oil pump drive.
- Modified a bimini to fit off the tower with quick release fittings- i realise its filthy, been sitting in the shed for years, should clean up ok.

Question time:
Its been so long since i pulled it appart i am not 100% on how the water lines run. Does this sound right?

Water in from jet- splits in two, one pipe into rach of the water cooled exhaust manifolds- one pipe out of each of the water cooled manifolds into the block (where the automotive water pump would usually fit)- out of the inlet manifold (where the automotive thermostat would usuall fit)- split into two to the exhaust output.

My old setup was to the front of the block where the water pump would be mounted first.
Then out of the intake manifold to the exhaust water jacket. Then into the exhaust.
It had the temp sender in a blanking where the thermostat went.

I'd run a cheap $10 strainer too, I blew a head gasket once from sand building up in the exhaust water jackets.

What are u using for hoses/fittings?

Yea ok- i had always presumed that the wayer goes through the water jackets in the exhaust manifolds first (so a hot engine isnt injected with cold water).

There are threaded inputs and outputs on the engine from its previous life- i was planning on hitting up the hose and fitting shop for threaded hose barbs and rubber flexible hose.

Yeah makes sense. I'd run it through the exhaust first n see how it runs.

Through the exhaust manifolds after it leaves the block defeats the purpose.
Best thing you can do for any engine is run a thermo control. Temp will be more stable and not so cold.

I thought it was to keep the temp down in the engine bay.
Looking at all the Merc diagrams on the net it goes through the manifolds last.
But in theory getting the water just below or close to running temp before going into the block sound like a good idea.

I was thinking the same think but that flexible hose is like $60 a meter.
I was thinking of doing something like this.

but using 3/4 copper and benders.

Your set-up is the most basic raw water cooling. The water from the jet / sand trap gets pre-heated by the exhaust manifolds then in the water pump ports on the block. Out the thermo split into exhaust gas. Block temp is regulated by a tap on the line to moderate flow rate. Ideally, some pressure regulation prior to entering the block. Jet can pump big pressure, far more than head gaskets are designed to contain.

A bit more on the boat- hector drove to perth to pick up some second hand (new) exhaust manifolds with risers at a bargain price while i i installed the fuel system. 40l hornet poly cell under the deck with fuel lines running underneath the floor to a water separator filter and high flow mechanical pump. My favourite part of the boat so far is the fuel filler scavenged off the old 'anyhow' taking pride of place on the bow.

Some more work on the boat.

- Sorted out cable brackets on both ends of the teleflex cable (throttle)
- Made new water lines from copper and brass fittings.

Hopefully a bit more over the weekend...

Another update.
Boat is wired
Bilge pumps and blower installed
All controlls work, its a thing.

The trim tabs seem awesome, hydraulically controlled by a small electric pump mounted in the engine bay. They have a neat monitor that is mounted to the right of the steering wheel so you can see where they are set. Not sure how usefull or not they will be, hopefully i will find out soon.

Sad story of the day.....
I tried to start the engine and found my dizzy faulty, borrowed a friends dizzy and then found no oil pressure.

Ordered a new oil pump and dizzy- praying the engine is not junked from running without oil pressure

Well done. Even the pros are calling it a great job. 8) 8)

Anything to report on the oil pressure issue?

Just unhooked everything and pulled engine out to change oul pump. I packed the new pump with vaseline, apparently it can help stop cavitation on initial start up.

I will prime via a drill tomorrow and hopefully get some oil pressure.

Ok, some success on the weekend.

Boat in the water and floats- there are a few leaks around the jet drive than need to be sorted, however nothing too major.

Got a drive in on Saturday, ran well, however steering cable and a few other components were a bit loose.

Tightened everything up and headed out for its first 'ski' on sunday, however it stumbled and miss fired- im guessing the old points ignition i borrowed from a wreck to get me going may not be working properly. New electronic dizzy is on the way.

Finally- on the drive home, the front axle on the trailer shifted laterally, killing a tyre against the spring hanger.

Worried about possible boat curse.

Hey Mof,
I had the boat out yesterday, pulled skiers and wakeboarders fine.

I did however notice that the shaft of the jet unit was getting hot- im presuming that is an issue. I will pull the rear bearing cover off and have a look.

Warm to quite warm is fine and normal. Stinking hot is not. Don't be tempted to over-grease the bearing i.e. too much or too often.

How did this happen?? Axle seats not welded on? U-bolts loose?
