Is a 150 EFI and 150 Optimax the same thing?

Thanks

No. the EFI injects fuel mix into the air stream going into the crankcase. The Optimax is direct injected; fuel is injected directly into the cylinder.

The opti is much more fuel efficient and cleaner.

Thanks, JB. It makes me proud that I presented a question that could be answered. Apparently that is not the case in some of my posts.
