Elite repair: +13 rep, +9 other.

Elite engineer: +13 eng, +9 other.

The former two add up to +22 rep per level.

Regular repair: +11/12 rep, +10/+9 other stuff.

Regular engineer: +11/12 eng, +10/9 other stuff.

If you have a +12 repairer and a +12 engineer with +10 rep you still get +22 rep per level.

If your +12 engineer has a better repair rate, say +11, you get more rep per level than with premium sailors.

I can probably sove olives on boosts vets experts from this event coming up :)
 

whats the difference between 5 and 4 engineers? unfortunately ive already started leveling 4 engis to like 60, and i dont really feel like repeating the process for one more eng =/

Do engys affect engine recharge? or is engine recharge the same as overheat time
