I am currently looking for a suitable engine for my new hull - its rated up to a .67 which I understand equates to 11cc.
Had a look though this site as well as the OMRC and I have found suppliers in the UK for both OPS and CMB engines but can any one tell me what other companies produce this size engine and were I can buy them (preferably in the UK)
I know K&B do but cannot find a supplier in the UK and have tried looking up Picco but unsuccessfully.
The hull will only be used for pleasure, so don't need a race engine so again any recommendations would be welcome.
the hull is designed for a central exhaust so the engine needs to have a front exhaust port, not a side exit
Cheers

Hi Dave,
Unfortunately, front (or rear - depending which way you look at it) exhaust engines do tend to be racing engine, as the main reasons are to allow a shorter pipe, and better gas-flow. Equally unfortunately, in the UK, it is really only OMRA who still run a .67 class. Picco are not producing .67s at the moment. K&B are now under Mecoa in the USA. I don't know of a UK distributor, and I think that supplies even in the US are fairly scarce. If you want a 10 or 11cc sport engine, I think it will have to be a side exhaust engine - with a wrap to centre type manifold - as BJ said. If you don't have the facilities yourself, I think Just Engines also make headers to order. A wrap to centre header though - even in a .61 size sport engine, is likely to result in longer than optimal pipe length, but then pipe length for that kind of engine is less critical than for a racing engine anyway.
If cost is the issue, you could maybe consider secondhand, but that in itself can be a minefield - with parts usually only being available for engines which are in production etc. CMB usually continue production / supply of parts for about two years after discontinuing a model, but don't expect that kind of post-sales support from all manufacturers.
Could I ask what the hull is ?

EDIT: Just seen the Scorpion thread, so it's all clearer now.
