What size ETEC?

[bradford]

I've decided to bite the bullet and retire the old 225 Evinrude. I've talked to few on here and read countless posts that a 150 is a good match for the V20. Being somewhat old school I looked at the left over carbed 2-stroke 150 yamahas and found that after it's all said and done I might as well buy an etec 150 and get a lot better mileage. Since I'm gonna break the bank on a new engine I've decided I'm gonna fix up the rest of the V to match. Part of this includes adding extended fuel capacity in the form of Reel's fuel tank/seat boxes which hold 39 gallons each. According to my calculations this will add approximately 550+/- lbs in fuel weight. Is a 150 with the right prop still a good match or would I be working the engine too much. I wouldn't always be hauling a full load of fuel, and it's usually just me and the wifey and rarely maybe 1 or 2 others. I don't need any crazy top speed, and always thought my 225 was overkill for the boat. I just want her to plane out nicely and get good fuel range. Any input from my imaginary friends here at Wellcraft V20 is always appreciated.
