Everybody STOP and take a breath................

I owned this model for 7 years.

The 1990-1995 Outrage 17 is very sensitive to stern weight and will NOT tolerate a bracket or twins.

Max engine hp is 120hp.

Lowest weight available is the ETEC 115.


I have removed 350lbs from the aft deck & I am building a composite cab. There is no substitute for accounting. Minus here, add there and still remain within safe operable limits.
For example:
1) Honda BF90= 380lbs and is a common motor on this boat well within design specs.
2) 350lbs have been removed from the aft deck (stern deck and gunnel cover, batts and fuel tank) will be relocated to maintain proper trim
3) 2 x Honda bf50= 450 lbs
Therefore 350lb+380lb= 730lb on aft deck as designed to operate with full tank of fuel.

I have removed 350lbs and adding only a net 70lbs in motors for a net weight difference of -280 approx.
There is a leverage movement to consider, however I am only adding 70lbs AT the transom. Removing the additional 350lbs from the aft deck area should more than compensate for this. Facts? Figures? Direct experiences?

Mahalo,
Mike
