Why does Illmore spec Pennzoil? Hmmm...Penske owns a stake of MC as well as owning Illmore Marine and guess who is a huge sponsored of Penske in the NASCAR world.....?Pennzoil (Joey Lagano #22) So knowing the very successful businessman Rodger Penske is, of course you would spec Pennzoil in all your engines your company has a stake in. (I have nothing agains Pennzoil, I just don't buy into you HAVE to use their oil or else.)
I run RP in the BroHo boats and never had an oil related issue.
As far as break-in, I have watched many a promo boat come to the lake with little or no hours on it. They get broken in skiing and never seen an issue. The only one I have heard of is taking a brand new engine and then just running at a steady high rpm for extended time. Tournament style skiing you never go more than 20 seconds or so, so no issue. OF
