We just sold our 1987 13 Super Sport with a 30 E-TEC. I thought it was the "perfect match" for the boat.
It replaced a 2000 Johnson 40 2-stroke. Only lost about 2-3 mph top end, but EVERYTHING else was a gain. (Quiet, smooth, instant starts, no smoke, sips gas, really sips hardly any XD-100 oil, great performance. Top end was 30-31mph with a 13" stainless 3 blade with the 30 E-TEC
There are two 13's nearby with 40 E-TECS.
My advice regarding the 40 E-TEC: Don't do it!!
240 pounds is too much. The 175-180 pounds of the 30 is actually just getting by. The splash well with the 30 had about 3" of water standing at rest. The other two 13's with the 40's had a pronounced "squat" at rest.
To make matters worse, even with engines raised, their props were in the saltwater and were constantly getting fouled, and the intakes were restricted with growth. Both owners had mentioned they regretted the decision to go with the 40's.
The boat closest to ours moved the battery and tanks forward, but didn't do enough to matter.
We have a good number of 13's in our vicinity. We were the first with a 30 E-TEC, and several others followed.
Every one I spoke to really enjoyed them. The 30 is a great companion to the 13.
