Im looking for feedback on the plan below, theres alot of great tech guys here that can advise.

Stock RF P500X2 has failed sending direct DC voltage to left side tower speakers, blowing speakers. I want to replace it with WS SynDX2.3 amp. giving 300 watts/speaker ( 4 icon 8)

Icon 8 have peak 300 watt and 150 RMS

Does this mean speaker will have 300 watts delivered from the amp all the time, or only when volume is high?

Also when im at it, the RF P400X4 amp for 8 cabin speakers is only delivering 50 watts per speaker. There is 4- 8" M282 with 100 watts RMS and 200 watts peak and the 4- 6.5"  are 75 watts RMS and 150 watts peak.

I want to  add WS Sinister SDX-4, this would up the watts to 170 watts per speaker. I know this will put some pressure on the 6.5" speakers, but were not blowing out the lake all day either.

Its overkill, but can be ready for speaker upgrades down the road.

Kind of like recirculating ball steering and bias ply tires, keeps you on your toes.  It would be a pretty good way to get drivers off their phones behind the wheel.

@85 Barefoot - one interesting and nice outcome of discarding 400+ lbs off my ski tractor is improved tracking.  The real reason is moving the center of gravity forward by a foot, the pitch difference at speed is noticeable.

LOL the delay is about the readiness of our home, not  the boat. 

But I'd thought about doing the delivery myself, I have to admit, as it's costing my son over $1500.  But sanity reigned, as it's a 12 hour drive and 735 miles (3 motel days, ~$350 in fuel, and 4 days' driving; I'll deal with moving from FL to GA, which is plenty to keep me busy), and he's happy to pay the shipper who's ready when we are - which keeps moving a day-at-a-time later (don't want to move in while the painters are doing their thing, or the floor's not yet laid, etc.)...

And, of course, our getting ready to leave FL forever keeps having chores and pleasures (goodbye dinners, etc.) accumulating or sprouting.

But we'll be there soon enough, and so will the boat ☺

LOL - yeah if that is your idea of a daily drive distance then definitely pay someone.

I have a 91 Malibu euro f3 (skier), recently the prop and shaft were bent and I am having problems finding replacement parts to have the boat ready for the 4th. Any suggestions I appreciate and thank you in advance. 

Yeah its on a pivot.  I think the Volvo part number is 3861169 and that they take the white plastic piece off of it.  It looks like it has that 7 sided nut below it.  I ordered one and will see if it looks the same.  Problem is they are also discontinued and $400-500 where I can find them.
