I got two quotes today to trade my '04 90hp Merc carbed 4 stroke for an '04 Merc 115 hp EFI 4 stroke:
$2,100 difference from one store, $2,200 from the other, In both cases I have to do the un-rigging of the 90, and the re-rigging of the 115. Seems like a lotta bucks for the extra 25hp. On the other hand, I would like the extra power. I really think the 90 is just not enough hp.

Can you guys who have done this give me your opinions about the reasonableness of these quotes?

BTW, this is for my '04 Montauk 170.

I think you know how I feel on this issue .
how many hours do ya have on your 90 now?
I personally think a reputable dealer will give you a fair shake...take in your trade and not beat ya up too bad.

all in all, I think you will be pleased...
labor wise...the throttle and shift cables will not have to be changed, If it is possible,,,unbolt the postive battery cable from the starter solenoid[relay] and the negative cable from the block. whaler uses 2 ga..motor from mercury comes with 4ga. let the dealer keep the battery cable with you trade.

this is a very easy swap....the tach pulse setting remains at 6p position, no change neccessary.

the new 115hp efi will need the the reducer adapter for the water pressure gauge hose connection to the block.

take note of the postion of the trim tab on your 90 and insure it is set to the same angle on the new gearcase

good'll be glad ya did!
