I have a '98 150HP Ocean Runner. Does it have the same specs (displacement, ignition, carbs, gear ratio etc) as the Fast Strike?

Saw that Infomercial on the E-TECs yesterday. One of their claims is that you can run 'em full throttle, out of the box, no break-in period required. Anyone have a comment on this? Also, another claim from the Pro Fisherman giving testamonials is that the added weight of the 4-cycle motors...

In the fifties and sixties Mercury and Johnson each championed different kinds of motor technologies. J/E had V engines, electric gear shifts and air and water controlled chokes. Mercury had inline engines, mechanical gear shifts and electric chokes. Right now, although a lot of these...

I have an '98 Johnson 150. I do not have a signal coming out of the voltage regulator/rectifier to run the Tach, but the motor is still charging the batteries. Is this possible?

I am purchasing a '98 150HP 60 degree V6 Johnson OB. It currently has an aluminum prop with one of those diffuser rings on the exhaust outlet. Since I was a Mercury owner, I need to ask: Can I use props without the diffuser ring? Am I getting the correct prop with this motor? I have a SS...

My neighbors Hobie cat banged into a piling during a storm and it put a good sized hole in the center of the starboard hull. The hole is 18"X30", with some of the hull pieces hanging by fiberglass "threads". Also the hull is a sandwich of thin fiberglass and foam core, and there is no access...

I am looking at the subject motor. I believe it to be 60 degree, loop charged V6. Does it also have oil injection that varies the gas-oil ratio, or is it a fixed ratio injection?

Some years Mercury made some solid-hub props, which did not have the thru-hub styling. Mercury intended the exhaust gases to cause the prop to slip (ventilation). Did these ever take off? Related question: If you install a prop from an inline Merc on a Mercruiser Alpha, the exhaust hub will...

With the advent of the XHS hubs, it appears that is woule be easy to change props from a Mercury hub to a Yamaha hub, as long as the propeller is the correct size for the gearcase. Specifically it appears that the V-6 Merc OB share props (but not hubs) with 150HP and above Yamaha Outboards. Is...

Conventional 2 cycle outboards have needle bearings for internal main bearings, crankpin bearing and wristpin bearings. 4 cycle auto engines have solid bearing surfaces. What do the HPDI outboards and 4 cycle outboards use for bearings?

I have a '88 Alpha 1 gen I outdrive that is progressively getting a shifting problem. Last year, my lower shift cable went bad (corroded enough so it wouldn't go in reverse), due to loss of the welsh plug on the OD. I fixed the welsh plug, and installed the new cable and everything worked well...

I used a GPS to determine my speed in my Avenger speedboat. I run a '77 Merc 1500 inline (2::1) gear ratio, a jackplate that has the AV plate 1-2" above the water, while on plane. I run an old 19" pitch Mercury SS 3 blade standard prop.Here are the results of my test. WOT = 5000, GPS Speed...

Some props are designated as "Bowlifters" some as "Sternlifters". What about the prop's design causes this?

I removed the hose from the lower crank case bleed valve and I get a few drops of white liquid. It smells like gas and soaks into a rag like gas, and could be the remants of the white grease I used to install the rod bearings mixed with fuel. It could also be water mixed with 2 cycle fuel...

Here is a synopsis of some of the SHT I have been part of.<br /><br />In my teens: Went water skiing a lot. Had a friend who liked to ski in a tuxedo tails jacket, nothing else. Not a real pretty sight. <br /><br />Took a busty friend waterskiing one day. We wore waterski belts in those...

I'm planning to install main and connecting rod bearings on my '88 205HP 4.3LX Mercruiser. The Mercruiser numbers are 23-818465 for a set of Main bearings, and 23-11992 for a single pair of connecting rod bearings. Is there a cross reference to automotive bearings? As usual the price...

The Oil pan on my '88 4.3LX sprung a leak. Can I use a standard automotive oil pan as a replacement? The dipstick is on the starboard side, does this make a difference?<br /><br />I plan to change the timing cover at the same time. Can I use the automotive version? Are "marine" gaskets...

Is it possible to replace the power trim/tilt hoses inside the boat without pulling the motor? I have not had any luck seeing where they attach to the sterndrive unit, but I assume they attach below the driveshaft to the inside of the transom plate. I also assume if I had long enough arms, I...

I was installing the prop on my 150HP Inline Merc. As I tightened the prop with a standard prop wrench, the thrust washer split in two pieces. Now, I'm not too strong, and didn't pull too hard on the wrench. What in the heck happened? Do they get brittle with age (or saltwater)?

Folks, I started my '88 4.3LX, and it ran poorly. Just for fun I pulled the spark plugs I had installed last summer and looked them over. Several had rounded electrode straps, and one was missing at least 3/16 of its center electrode. It appeared to be burned away. I replaced them, and the...
