Thundercat built thread!

Almost finished cleaning up today.

Got the engine painted, cleaned all the electrics and base tray. Looks a million times better than it did!

Replaced some of the bolts for clean new ones too.

I've also primed the pull start housing ready for some colour.



Will begin deep cleaning the outside of the engine this weekend!

came up alright! looks good

[lukewhiting]

Just finished cleaning the hull today using a cleaning kit from ribshop!

Worked wonders!

[lukewhiting]

It lives!!!! Third pull and it started!

But lump and smokey to start but once water up it runs pretty good.

Definitely needs a good service but it runs!

May go out later for a quick test!

[lukewhiting]

One thing I have noticed so far is the the tell tale pumps abit i regularly.

Brand new water pump is fitted fine. It's fine on tick over but once revved the flow decreases a lot?

Could this just be due to there not being enough pressure from the hose pipe

[lukewhiting]

Found the issue...the hose connection was on properly...DOH!!

All fine now!

First day of testing today.

Went out with two mates in a zapcat and jetski.

Didn't all go to plan!!

Engine idle is alittle too low and has a fuelling problem. Engine runs lovely and smooth but doesn't rev high. Only got a top speed of 28mph.

I think it's the carbs as every now and then it worked fine. Also on my own with a lighter boat going head to wind it was much better but still not revving.

Will be testing the coils tomorrow to check it's not them.

[lukewhiting]

The past week I managed to strip down the carbs.

Nothing major to report other than the mixtures being abit too rich. All fairly clean! Also raised the idle up alittle.

Fitted new ngk iridium plugs and already running smoother.

Starting to play around with engine height alittle now too. Bit of a cave man method but have made up some measured blocks of wood to sit the engine on.

Have made a few to raise them engine between 35-50mm.

Out for another test tomorrow!

[lukewhiting]

So yesterday was successful!

Engine ran without any faults! Didn't get a chance to play around with engine height but seemed pretty good as is now.

Reached a top speed of 43mph which is a fair pace for a standard engine and a worn propeller!

Couple more things to buy then I can begin to modify for some extra speed!

[lukewhiting]

Long time since and update but getting some stalling issues still. Have ruled out fuel tank & line, and everything before the carbs.

Definitely fuel related not electrical.

[lukewhiting]

Engines issues all sorted!

Got it out for a test yesterday and all went perfectly.

New prop ran fantastic but forgot to get a speed reading. Now finally some modifications can begin!

[lukewhiting]

[watersidemat]

Nice looking boat, glad it's running good.👍

[Roflhat]

What prop are you running?

[lukewhiting]

Can't remember now but I think it's a 15p prop, unsure of make! Whatever it is it seems to push on well!

Also got a powrrtech and and old Solas

10-3/4 15p lifter semi-cleaver. Still not sure on make though

[Roflhat]

Interesting blade shape, looks like it's been cut before

[lukewhiting]

So got out for another proper run since before xmas.

Safe to say she's all set up perfectly now! Just needs a steering damper and she'll be ready for some mods to squeeze some extra mph!

Got some good photos too...

[jeffstevens763@g]

great shots luke & great fun i bet

[watersidemat]

Looks class. Can't wait to get some time off at home so I can get mine in some form of working order. For some impressive height off that small wave too!
