White hull with black wing tips and windscreen. Livorsi gauges including gps speedo, stainless marine trim unit, and hydraulic jackplate. Hydraulic steering with 6345 allison cylinder. Side slide steering excel. Boat is in showroom condition. 2005 280 ss. Factory mid that has not been cut...

When I had my 20" 225x the plates were very slightly worn. The mounts were actually worn more than the plates. If it is not fixed quickly the plates will continue to wear. It seems to be a common problem with them for whatever reason.

Do you get consistent numbers when your final set it clockwise? I have been told the way to do it is the first way you mentioned. Unfortuantely, if you look around or listen to different people you will get every answer. There are a group that says leakdown tests are the best one to do...

No I didn't rock it. Was looking at the gauge and rotated flywheel correct direction until hand stopped moving. Are you supposed to rock them?

Compression is 144 and 145 on all cylinders. 5 cylinders show 3-5% leakdown and 4 cylinder shows 6-8%. 18 hours on motor. Not sure if it will get better, worse, or stay the same for a while. Guess I will keep my eye on it.

It could have a hole in the block and it wouldn't go there! Lol

When you guys do them... do you pull all the sparkplugs out or leave the ones in you aren't testing?

The model boat drastically changes fuel mileage as well. I can get 4.5-5mpg with a 280 on my ss. 225x would get 5-5.5mpg. If you can get 6-7mpg with a 3L on a xb21 that is doing real well.

Is this a 1 day event?

Probably Chris (Robo) The boat looked great in the pics I saw of his.

Haha

No way a ss is running 120 with a 280. I could believe 110-112. A good 225 will run 100-102 on an ss.

I did notice water coming from both exit holes on your promax which is not normal. Looked like most 260/280/drags.

Mine looks very similar to that one.

I would run a blend. Mercury premium + would be my choice.

Talk to Chris (Lake Anna) He has a mint 225x he may be willing to trade you.

Look out! Lol.

Look at it this way... if you toast it that gives you another reason to get a 280.
