Saving Old Seagulls

Hi all. Just wondering which power head is more powerfull,
a 102 or an efnr. i.e. from the point of view of racing.

Difficult question.

The 102 has a better looking gearbox, but I would guess that the ENFR has a more powerfull powerhead, so try them both on the same hull then swop around the gearboxes & try again.

For this test you might well need a GPS & a rev counter, for a definative answer.

efnr it is then. thanks Charles.

If you decide against the EFNR gearbox for your racing Let us talk further I am looking for just that gearbox
