I've seen a few references to Yamaha 225 but I thought it was relatively heavy. I'm guessing that there isn't as much after market tweakabilty as a Merc too.
As far as arguement between Phantom and Ring, is there really much to choose between them for mere mortals not trying to extract the last 10% ? And as for length, is the benefit of 21 over 20 over 18 (or whatever) primarily in ability to handle a chop or are there other subtle benefits (general balance, stability at speed....) ?

A Phantom 18 with a healthy Mercury 200 (not an XR2) should easily do 70+ and the engine should last a long time as its not one of Mercury's race motors. My Mercury 200 powerhead is 25 this year
A well setup P20 should do about 70 mph with a Mercury 200 but I would think you would need something like a Mercury 225 Promax to get a P21 going that fast. If you wan't longevity and reliability stay away from the race motors like the 2.5 Offshore and the XR2.
All things being equal the bigger the boat the better and more stable it will be in a rough sea as the waves will effectively be smaller!!!
From what you put in your original post I'd go with a P18 and Mercury 200 as new and in as best condition as you can afford.

I wouldn't have said the 2.5efi should be mentioned in a thread with the word "reliable" in the title.
IMVHO, reliably going over 70mph is easy. The only question is how much money do ya want to spend, and how big a boat do you want.

Hi guys,
How long would the new Merc motors be expected to last?
Thinking of a 200xs in particular

With reference to Rinker 236 and Mercruiser 7.4 (454 Magnum) 365hp - I had experience of driving 3 similar ones.
First one was the first that Rinker produced and was the fastest at just over 70mph. I then had one which didn't quite make 70 while my brothers was a shade slower at about 68mph. The engine was mounted slightly higher in first boat to the point that the fibreglass skin on the underside of the sundeck was cut away (in a not too professional way) to get the extra height in. They subsequently lowered the engine a little to get under the standard sundeck but I feel this contributed to slowing the boat down a little.
All three were fun and rock solid at speed. Walking around at 70mph on water ! Perfectly stable ! And what a gorgeous sound flat out with the "silent choice" off ! I don't remember what the prop pitch was, but it was pitched for speed. Getting it up on plane wasn't the quickest but once there it was nice and responsive.
Having read some of the adverse comments about reliability of high hp outboats I'm wondering if I should reconsider sticking to inbords. I just didn't want anything too large or heavy.

Not that you are biased !!
Thanks for info and photo of your boat. Sounds great. Not convinced yet that I need to go 21 and higher output engine. Is your price UK pound or Euro ? And where is it located ?

Many thanks for opinion. It makes great sense and seems to fit the bill. Any nice examples out there on the market ?
For my further education, you refer to an old 200 powerhead. This is presumably from a time when outboards were rated by power at crank as oposed to prop. Would this make it closer to a 175 in todays money ?

Burty, the link should work! It may take a while if your on dial up it's 25 mb. A mate shot the vid from the passenger seat, it was his first time in the boat.
BTW, What's a RH moment?
Alan
Here's said mates boat, thought you guys might like it, Phantom 16 with a 175, cant wait to start setting it up with a plate and decent prop

From what I've seen the P20 (only seen Mutz Nutz) is more of a longer P18 whilst the P21 (uncle's got one) has more depth and beam as well as that extra bit of length making it much more stable, settled and able to make the gaps in a large chop.
If you are worried about having to increase the power due to the extra size then maybe seeking one of the featherlight P21's could help solve this?
Hope this helps you in making your choice
