Any other thoughts? do i need hydraulic steering with 550hp?
If so what brand and what is the cost?

Are gaskets, new valves (SS & Inconel), valve springs, locks and retainers included? How about all the machining like align hone, cylinder honing, valve job, refitting the intake manifold runners to the new heads (welded, putty or nothing?), valve guide clearances, re-surface the deck and heads and intake manifold? Balance rotating assembly? Is the oil pump blueprinted? Compression ratio? etc, etc....Your labor quote looks really light for a quality job. Do this job right, you are looking at 100+ hours preparation, machining and assembly time.
If what you have listed is his entire proposal, I would keep looking. It is all about the work, not the parts. Would it be possible to get the names of three of this builders marine customers for references?
Who is doing the final painting and marinization?
I don't want to be negative...but i don't think you can get what you are looking for at this price point. I learned the hard way...

Thanks for the input so far. Any other input? also should i go with Hydraulic steering, or can i stick with the stock Bravo setup for steering?

I am building a 650Hp Outlaw and I am going with full hydra ext. dual ram steering. In my opinion with the size of your boat and that HP you can probably get away with a single ram full hydra. Maybe even just an add on.

what would be a good add on unit? i am clueless...

thanks for the help,

I would go full hydraulic right off the bat. We bought my 24' Superboat with internal cable/external hydraulic assist. The inside parts were worn out when we bought it late last year and we just installed the internal kit so now we have full hydraulic. It is an AMAZING difference between the two.

The internal kit we bought is a Zeiger that we picked up from Fred at Trick Marine. The kit was top notch, and the best part is that Fred will give you Paul Zeiger's phone number and he will walk you through the install step by step if necessary. Paul Zeiger is a class act and you can bet that any steering items I need to buy wiill come from him from now on.

full hydraulic all the way . duall ram jus had it done the best 6000 grand i ever spent.

buffexec 05-29-2007 10:22 PM

Jayhawk, what kit did you pick up and how much did it cost? how long and difficult to install? etc.
