At moment i lost no idea about Power over 700 HP!
That is much enough for an XR ,with Driveguardian or not!
There are some other works that must be mach before! ITS Box sounds very good for me to as i love the clear look!
But first all must run and then see what next winter brings.
By the way,the 700sci have same valves and rockers,so they not to bad first time.
I think only about new springs at moment,as the 50 hours old engine stands now for 7 years.so better change springs or not????
But thanks for all tipps!

Yes the 700 and 600 are very similar. I believe cam, intercooler and evening are the only differences. And if you talk to many who have worked with theses motors they’ll say the stock valve train is questionable at best in these motors. There were a run of the rockers that went into these motors that fell apart, dropping needle bearings etc everywhere. Not trying to scare you or get you worried, just sharing some things I’ve found through my research. If it were me I would change the springs, stock replacement should be fine, and I would replace the rockers as well. Much easier to do these things before she goes in the boat.

Either way way that’s a cool motor you got and that’ll be a fun ride! Looking forward to watching your progress.

Hello.
I am happy about all infos like this about the rockers.I am one of the safe drivers that try to do all that get no fault at driving.Can say i have all sensors,starter,lightmaschine,boostvalve and much more,maybe all electric parts from the engine in my boat!!!
Also have buy orginal connectors from the IAC vent and build an wireparts with 1A Fuse to stick between as i read there is a problem.When IAC fault,it kills often the PCM.Must buy 15 connectors in and 15 out,so if someone needs this wires with fuse and orginal connectors,get back to me. i have build some sets.

Also i have checked long time the diffrences between 600/662/700 SCi.
Only the first series 600 SCi up to engine nummber 0M962885 has a 10mm lower intercooler.All 600 after this nummber have all same intercooler like 662 and 700sci..But the older 600sci have same power options,as this aford it not real.I have ask what makes an update from intercoolers,as the newer will fit,but all say makes nothing.
best ist to look for more waterflow in every from this inercoolers.(i work on this).
For example 662 has only other software and an other pulley on the supercharger! Not more.I have ched partlist long time!!
So only first serien from 600sci have 20mm shorter belt for the charger(10mm lower so 2x 10mm shorter belt!

My engine was build 2008 ,first series 600sci,but get end 2010 complet new longblock and headers from merc in warranty(cmi old series crack and kill the engine in the warranty time).first they mount new lonblock with new old cmi series,but before 10 hours they change again the cmi for new version.
In this condition the engine stand now 7 years iconserved and winteringsized in warm shop.
an idea how i can look if i have this bad rockers now?? the have only run 50 hours and made 2010.

best regards.

You can post pics without being a member, I upload mine to photobucket then drop in the direct link here and they show. Had to do the same thing when I was a platinum member after the change so now sure what I was paying for...? Was told that’d be fixed a number of times but it never ways. Anyways. Here’s a little motivation for you. Still working on dialing mine in... 2005 25 Outlaw. From what I’ve read the 275 and 25 bottom halves were very similar.

I try to put an link in my my baja with my old,now sold engine! can you see it? michael

I get this 275 near new with 49 hours on 496 Ho but the work from Baja to install all technic was extrem poor.I like it im my way much more.

Here some more pics from the boat! I get it end 2016 in 100% standart like it come from baja.All changes made by me!When engine runs,i like to add hydraulic steerind,maybe ITS and then some more things like big tabs and so!

Yeah i build a good replica from an 520 with my 8.2!! Runs very good with biggest Whipple PCM update and CMI.I see 73 Mls best on the Ecomonitor with added GPS.
The 496 was first that gone after buy the boat.Then clean engineroom,close all holes and so!I make some alloy plates fitting,but mount not last winter as i want the powerdecoat first and then make in!
