I've been trying to tell folks for years how much more efficient the SeaCraft VDH is compared to modern hulls!

I think Sandy's right, but it's not just the horsepower wars that have warped our thinking . . . the wide beam required on modern boats to support the heavy new motors screws up the ride, so the designers then increase deadrise to get the soft ride back, but that takes a lot more power to get it up on plane, etc., and a vicious circle begins! Fortunately for us SeaCraft addicts, Carl Moesly figured all that over half a century ago! On an 18-20' SeaCraft hull, light is right, and "more power" is the enemy of good enough!

Thanks for the comments!

The 1988 Yamaha 90hp is 270 lbs.

Lightest modern replacement would be an Etec 90 (320lbs), a 1990s Evinrude 110-140 hp (306-315 lbs), or a 2000's Tohatsu 90. I think the old Merc 100 was 265 lbs also.

I heard that the Etec is being phased out in favor of G2 4-stroke technology. Too bad for SF owners!

Beware of what you hear on the internet!

Although the G2 E-TEC has better performance and lower emissions than 4-strokes due to a total clean sheet redesign, it's actually still 2-stroke technology! (with provisions in the design for a catalyst if the EPA ever mandates that like they have for I/O's!) Although weight increased 41 lbs between the 300 hp G1 and G2 versions, the G2 weight also includes at least 25 lbs for a 2 gallon oil tank mounted on motor, hydraulic power steering, plus electronic shift & throttle that's not included on the G1 version, and they're still lighter than competing 4-strokes. They are supposed to reveal a G2 version of the smaller 2.6L 135/150/175/200 V-6 motors in the next couple weeks, so will be interesting to see what happens to weight on them!

The 390/405 lb (20/25") 115 hp V-4 is now the least weight-competitive G1 model, so there was speculation that it would be the next one to get the G2 upgrade, but evidently volume on the small V-6 is so much higher that the decision was a no-brainer from an ROI standpoint. I'm sure Terry England will be glad to hear that there are no plans to phase out the very competitive 90 hp E-TEC!

I heard they were having lots of trouble with new G-2, 4 stroke cam chain adjustment, oil cooler base corrosion, valve seats and "Dipsticks" - I read it on the Internet!

Then it must be true.
