WOW - that's some BAD stuff goin' on there!!!!!!!!!!!
Help is on the way - go to the vendor forum and look for "Shipyard Island Marine" - they are a Yamaha dealer and Andy is GREAT to work with - gives discounts to THTer's, too!

He carries everything from parts to complete motors! Not sure if you can get the "handle only", but if it can be done, ANDY will do it!
Looks like he ALSO has some "cowlings" on sale!
LOTS of folks here have dealt with Andy - including myself - and he's a GREAT customer-oriented guy!
Good luck on the "refit"!
Regards,
