Okay guys...this has probably been addressed but I didn't find it!!! My question is, will a seca engine bolt into a regular XS??????? I haven't had the time to really study the similarities and differences yet....but I picked up a butchered Seca and need a motor for my XS360. Think it'll work?????
 
Nope...Totally different. The only thing they have in common is that they are made by Yamaha...
 
The engines are interchangeable. My old SECA had a Maxim 5 speed engine. It didn't require any changes to the wiring or carburetors.
