    Engine Selection HELP

    Looking for advice on the following: Currently have 2 Honda 150hp engines (1) overheating (the other) runs okay. So do I invest into another 150hp (likely Mercury) to replace the Honda? OR Invest into say 300hp to replace both Honda's? Or 2 Mercury 150's. My concern with keeping the good...

    Twin BF150 and counter rotation

    To confirm the Port engine rotates clockwise while Starboard counterclockwise. So if I replace these 2 with a single 300hp which rotation do I want? I'm guessing standard CW.

    BF150 Overheating Continues

    Assume everything known to man was done. The past season engine still overheats, but did find later in season when water temperature dropped 10 degrees engine would not shut down at high RPMs (as it did when water temperatures were higher). So considering placing water scoops facing forward...

    Twin BF150and VTEC

    Here is the situation: One Engine which engages the VTEC Overheats. The other engine fails to engage the VTEC mode but does run upto 5K RPM without overheating. So could the engine that is not energizing the VTEC be causing strain on the engine that does energize VTEC then overheats? I been...

    BF150 Fuel Ratio adjustment

    My BP150 engine is running lean I believe and is generating extreme exhaust temperatures. Just an FYI the entire water system has been replaced and internal water passengers cleaned as well. However, assume that cooling is not the issue. Since the engine is controlled by the ECM based on...

    BF150 Barometric Sensor

    I was wonder if anyone knew the operational range of this device in terms of the pressure equated to voltage? The manual defines a several voltages of the device (Voltage low, High, Shorted,etc) but at what Baro Pressure? (Sea Level?) I'm looking for the Barometric value for the different voltages.

    VTEC Testing

    I was wondering if it would be possible to energize the VTEC solenoid manually with engine idling? I understand the operation of the VTEC system, however on this engine it is not engaging above 3000 RPM and well upto 4000 RPM. I have the brother of this engine (second BF150) and the VTEC works...

    BF150 Over Heating Part 2

    I have a long history with this issue. This past winter engine overhaul, all water passages cleaned and checked. New fuel injectors (not that I had fuel issue), new water pump (3rd one), new thermostats, checked resistances on temp sensors. This time I installed external Oil Cooler and also...

    BF150 Speed Sensor in gear box?

    I got this small hose running from somewhere in the engine down to the propellor gearbox housing. The manual says it is for the Speed Sensor, however this is an air hose. Anyone have any idea what is in the gear box that measures this? And any idea why it is needed? I have tachometers for...

    BF 150 Compression Issue

    In troubleshooting overheating in exhaust I broke down engine and removed the head, prior in doing so I did a compression test with these resuts (1- 140, 2 -125, 3-125, 4-130). Pulled head to clean water jacket and water passanges in the head. Cleaned all surfaces for new head gasket and...

    BF150 Excessive Exhaust Valve Clearance

    As my saga into engine overheating continues (BF 150 Overheating), I have noticed in checking valve clearances that cylinder 1 has a much larger gap between Cam and valve stem. Mechanically valve and cam work just fine. Note: Cylinder #1 has compression test of about 140 psi Wondering if the...

    Bf150 vtec

    Likely I will be asking a dumb question here. Here it goes: Since there are 2 Intake Valves that are controller by the VTEC system. So, the gap on each valve WILL or WILL NOT be the same? (Value 0.021 to 0.025) No detail in the service manual.

    BF150 Fuel Injectors

    This is one of those situations do I fix them even though they aren't broken? This is a 2010 Engine and haven't had any injector issues (knock on wood) and I currently have the head removed so access is relatively easy. So, replace or not to replace is my dilemma

    BF150 Crank End Play

    I have seen a couple of threads discussing this situation. However in my case although the crank has dropped down allowing the alternator drive pully to wear down the crank postion sensor and some of the timing chain cover. Therefore the thrust washers/bearings are not working as designed. But...
