I wish ! I was stunned at how much the dealer wanted - so ordered some cheap off t'internet. Then threw my toys out of the boat when it wouldn't start one day (not related to plugs) & I missed most of th cowes - tor- cowes race and towed the boat to the yard and told them ' bloody fix it or keep & sell it' . They then stuck new plugs in as part of the 300hour service and I had a few spares arrive in the post the next day !

The oil level will Not stop the engine from starting, it would just put it into guardian mode limiting your rpm. There is an oil level switch on the header tank (engine tank).
I had the feeling the Opti's oil sstem might be a bit more High tech than my usual power plants......

Watch you sont end up with bits dropping into the cylinder.

It might be worth stripping the head off to get this done properly as suggested.

Was the thread of this plug tight when you unscrewed it from the head?

Yes, it was the port were the plug snapped as I tried to unscrew it.
It is the middle port on the left (port side) bank of the block.
The plug is very rusty.
Ironically the plug below is in pretty good condition.

I'd go with getting the head off & doing it properly . I considered the 'simple/ cheap' way - but decided I dont want to destroy the bores/ engine/ head for the sake of a few hundred quid to pay someone else to do it all right .

If its not right it'll cost BIG money to put right after you grind up the swarf in the cylinder.

If it was tight when it came out - it may be that it was x-threaded for a while - hence the 'rust' colour on it - but I know they angles are a bugger to get right when you screw them in or out ! I snapped a new one just as I lent on the plug spanner abit in the wrong direction!

Just my opinion - but hope it works out well .
