So, as many will know already, I have a pretty brisk boat with a 5.0 Mpi Merc.
The engine is a great thing when not throwing sensor issues at me and is in great condition....
Only thing is that I have a never ending urge to get a little more speed out of her and would love to break the 70mph barrier. I am aware that this is a huge barrier to break in real terms and hp to weight proportions.
On a good day, she will get well into the 60's and has even seen 66.7 gps with a 21" prop...problem was that the 21" was pretty useless in all other areas.
So, the problem is....
I was recently walking through the workshop door of the local Merc dealer....when I was presented with a lovely big 350mpi still in the crate...he then told me it would slot straight into my boat no problem and align with the Corsa Marine exhaust perfectly, as the 5.0 does. Man, I'm so tempted but as far as I am les to believe, my 5.0 has a cam from new so might the difference be so small I may not notice the difference and just find myself ?10000 out of pocket ? Will the 350 really make all that much of a difference ? It may turn the 21" better I suppose ?
Further to this...it begs the question...if I go this far...do I go for the 6.2 mpi ? Would this slot straight in and is the extra 20hp (I think) worth the extra fuel she will sook over the 350 ?
Thoughts please ? Tell me I'm being daft...please !
