I have dual 1985-85 Mercruiser 228 GM 305's Believe they have about 350 hours a piece on them. Everything seems to be running great. I was contemplating on the next oil change to run Sea-foam in the oil prior to changing. Is it worth doing it, or just leave well enough alone and do a regular...
Ok, I understand about as much as I thought I needed to know about Props and choosing the right one for your application.
Although I am a bit confused about what I am seeing in my setup. I am currently running a Propco S24 14X18 Aluminum prop and the 225 OMC GM 307 is still able to rap up the...

I have been doing a lot of searching and have not found anything difinitive in solving the tilt problem for those old stringer electric shift drives.
I can't read the serial form my drive, but it is a 1974 OMC high profile stringer, electric shift without the true course steering. It shift and...
I am going to be getting into the process of finding a suitable location for a shoot thru the hull application for my transducer.<br /><br />I was wondering if some of you could share some tips and tricks for what to do to initially locate a good location. I.E. How did you hold the transducer in...
I am getting a very quiet backfire around idle to 1500 rpm or so, no sound whatsoever from engine. The backfire is not toally constant and occures once about every second or 2(very quiet, but I can hear it) I don't recal this from running it before.<br /><br />The only thing I have done...
While reading a lot of posts either to educate myself or troubleshoot a problem I was having, I couldn't keep thinking how useful it would be to have a new icon that is editable by the poster to show a completed solution in thier thread.<br /><br />This obviously would rely on the poster to...
Recently replaced my original Prestolite Alternator on my 1973 225 OMC with a one wire. The voltmeter on the boat never read more than about 11 volts, regardlessof if running or not. Previos to replacing the alternator, it was evident that the voltage on the boats meter(not perfectly acurate)...
I have a matrix 27 fish finder, and am trying to locate the correct location for the transducer. I have a rather aggresive v hull, even in the back of the boat. Currently while running over pretty much displacement speed, I believe the tranducer is too high off the water and just reads...
I was just wondering what your best MPG(not gallons per hour)RPM is with a 5.0 V8? I am just getting mine back into shape, its an old engine. got the 8th cylinder working yesterday(defective plug) and was going to take it for a spin in a bit.<br /><br />I found with the 7 cylinders at about...
I wanted to ask a question relating to RPM and speed as it relates to the power and torque output of the engine.<br /><br />All things being equal, prop trim, boat wieght, atmospheric conditions, water surface. If your engine is able to turn 4000RPM and achieve 35 MPH. is it possible that...
Had the boat out and engine seemed to run great, sounded good anyhow, but seemed to lack a little power. I noticed the timing wasn't advancing so I tackled that and while working on that decided to check the plugs and gaps.<br /><br />Took out the 3 plug and it was wet while all the others were...
I need to work on my timing advance. I know what to do and why I need to do it, but doing a lot of research on what advance timing is and how far it should be set has me a little confused.<br /><br />I know if it starts predetonation and pings you have gone to far, so that is a dirty, kind of...
I am going to poke around more with it tomorrow, but I took my malory YL series flatcap distributor apart and cleaned all the springs and weights and such. Everything nice and clean and moves, till I place the plate back on it and the wieghts seem to be bound in the channels that allow them to...
You are in luck, I just finished installing my smart tabs an hour or so ago. Per those instructions they install a 1/2 inch from the bottom of the boat and out as close to the chine as you can get them. Depending on what your hull looks like that is where the horizontal bottom of the boat...
