Avon 320 Jet Rib starter motor

[vlad the slayer]

Hi there I have an 2004 Avon 320 jet rib ( Yamaha 70/80 horse stroker )
I need a new starter motor and exhaust manifold gasket, does anyone know where I can purchase these two items .
The starter motor has been removed and is knackered, the only info on it
( mitsuba sm-13 12v )
have googled this and it seems there are many variations of this model, I need NEW not used or reconditioned.
If anyone can help it will be very much appreciated.

Bit late but try N&C they will need details of the motor assuming it’s a 701 yam https://www.ncjetski.co.uk/
