HEllo Folks My engine is a 1999 Johnson V4. It is on a 1997 16 ft Alumacraft Dominator. The boat is rated for an 80hp motor. I could not find an 80 hp so I went 10 over. The motor is used and has plenty of power. I have had no problems with it. However, I since have the several questions listed below<br /><br />1. I have heard that it is good to run Ficht Ram Oil because of the CarbX additive. I want to do this however am unsure if it is a good idea with this motor. Is it a good idea or not.<br /><br />2. The motor at WOT reaches 5000 RPM. I tilt it all the way up and can not get it to the maximum 5500 RPM. I have read in prior post that the motor will not last long if it does not reach the capable 5500 RPM. The Motor came off of a 18 Ft Princraft and was owned by an outboard mechanic. I am assuming he had it set up right. The motor has the same aluminum 17 pitch prop on it. I figured I was going to have to by a new prop. Anyway, It hangs on the transom at the lowest available setting and the anti cav plate is about 1/2 inch above the keel line if not aligned with it. My question is should I even mess with the setup. Like I said it gets to 5000 Rpm and runs at 60 to 65 mph. plenty fast for me.<br /><br />3. I winterized the motor using 2 + 4 in the gas. Ran the boat for 15 minutes or so and then fogged it using OMS fogger the kind you screw into the shrader valve. I was told to run the boat and pour the fogging oil to it till she stalled. I didn't do that. What I did was shut her down when she started to dog. I then sprayed a little in ech cylender and turned it over a few times with out the plugs in it to avoid it firing up. My questions are did I do this right. Does the fogging oil actually go into the carb bowl threw the shrader valve and what should I do in the spring to make sure it fires up and is not gummed up.<br /><br />I will appreciate any advise on these issues and one more question while we are at it is this a cross flow or a looper, a 90 degree or a 60 degree and what does that mean to me as far as performance.
