[pair of jacks]

I just went thru a repower last summer. Have a 2000 21 that came new with 200 Opti. After issues with Opti decided to repower- all your points are correct- 4 strokes are too heavy for this model and I didn't want to go with another Merc- So, went with a 175 E-tec. Now have about 180 hrs on it- great motor, very quiet, good on gas. But- in retrospect I wish I had gone with a 200 Etec. Top end is 31 kts. @ 5400 rpm's which is fast enough for me, but boat just feels a little underpowered. Cruise is 23 kts. @ 4800 rpms. I used to cruise at 23 kts. @ 4000 rpms with Opti. Like I said, boat just feels a little slugish unless you are at fairly high rpms. I tried to save some $ by going with 175 and since the year after I bought my boat SeaCraft starting selling the 21 with 150's on them as standard I expected the 175 to be fine. Always thought the 200 was more than I needed but it was probably the right fit. Like I said, overall very satisfied with engine but would be totally satisfied with a little more power.
