End of first season with this boat so first service. Have been quoted £1500 for winterising, full service of both engines, drives of and back to workshop for service, re-commission. Does this seem about right? Have asked them to quote for the most comprehensive service these engines can have.

Company is Volvo Penta agent.

Thanks

Seems about the normal cost from most main dealers, the valve clearance issue keeps coming up on this forum, so check this is included in the service cost.
 
Makes me glad I only have a weenie KAD32. €400 will buy me all the service items (including bellows and anodes) and decent oil for the season

Oh, DIY saves a few quid I suspect. Only thing i'm leaving to my mechanic is the valve clearance (Which he said he'll do for a 6 pack, sweet)

Why do you leave the valve clearance to your mechanic? Is it particularly tricky to do on that engine?

I think as long as you've done it before on motorbikes or old bangers then quite straightforward (on the KAD43). You will need a deep 10mm socket to get to the rocker box covers and a 21mm socket, with a 2inch extension, to turn the crank. Set both valves to .040mm (16thou)
Different story I believe on KAD44's, 300's etc
Will take a couple of hours for both engines. Should be done every 200 hours.
 
KAD32 valve clearances

There must be a number of people out there, including me, who would like to check/reset their valve clearances on their KAD32s. It does not seem to be covered in the owner's manual.
Is anybody able to give us step by step instructions, please?
Engine hot or engine cold?
Which cylinder with both valves open corresponds with which one to check?
Torque settings to respect?
All contributions will be gratefully received.

I think I used to be indecisive, but now I am not sure.
 
KAD32 Tappet Adjustment

Its always the paired cylinder on in line engines,

Rocking 1 3 4 2

Adjust- 4 2 1 3

Rocking means that the inlet valve and exhaust valve rockers are moving as you rotate the crankshaft back and fore a small amount- one valve opening, the other shutting.

Find the exact mid- point, if necessary feel the rockers with your finger, and adjust the valves on the other cylinder in the sequence.
By definition, if the rockers are moving, the clearance is zero...so don't adjust those ones!

Think of the four stroke cycle, the cyinder you adjust is about to fire so the valves are firmly shut, (a clearance exists between the valve and rocker as the spring does its job ) and the cylinder rocking is changing from exhaust to inlet stroke
