    Raw water pump kit differences

    Yeah I wish I could find the thread where the guy was bitching about not being able to change his alpha out on the water like you might be able to do with a crank driven pump... when asked what impellers he was blowing through he was using cheap aftermarket ones...

    Raw water pump kit differences

    Merc kit probably includes the housing - what drive is this for? normally say for a gen 2 they offer a kit with with impeller wear plate and gaskets . If for a gen one they use a plastic housing that I would replace but the stainless housing on a Gen 2 dont need to replace unless it was run way...

    1989 Mercruiser 4.3 LX, Alpha 1 Gen 1 Overheating

    Given your comments on the impeller start there... rule it out as it is the most basic part of the system. Use Oem parts, even “good” aftermarket parts like sierra dont have the lifespan of the oem merc parts. When i had a gen one, i found the sierra impellers lasted half as long as the oem...

    Fuel dumping in 5.0 cobra 1994 mechanical pump, not electric.

    You can get a fuel pump gauge at auto store or amazon very cheap some autoparts stores will loan or rent them. Some replacement fuel pumps are also too high in output pressure. I have seen this myself. You likely need to replace float and needle and seat with good quality parts Mikes carb...

    1989 Mercruiser 4.3 LX, Alpha 1 Gen 1 Overheating

    Verify temp gauge is accurate with a IR gun. What's the history of impeller on this drive are you using OEM parts for impellers and housings? Verify PS cooler is clear. What is history of thermostat in this engine and does it have the check balls in T on thermostat housing if they dont close...

    4.3LX TB IV timing advance issues

    do a little research and see if you can find a factory manual I might be off a few degrees from spec but should be in between the ditches... IIRC total timing should be like 22-24 degrees on it. You can do a little math based on balancer diameter if you don't have multiple marks on the cover or...

    4.3LX TB IV timing advance issues

    I don't know the specs for you boat but you likely have a 8 dge BTDC intial setting, then somewhere around 22-24 degrees total at like 2800 rpm. Hook up a timing light with an advance feature and rev it up to about 3 k. you should see the timing advance to keep the it on the timing mark...

    Chaparral Mercruiser Prop Question

    I wasn't counting that close.... Your use is similar to mine I have a 2004 Sea Ray 200 sport (20.5') with a 5.0 Carbed engine (about 240-260 hp as It is a 4 bbl Edlebrock carb). It was a 4.3 boat that I repowered so it has the steeper V6 drive ratio (1.81:1). I run a 21" Revolution 4 prop...

    Chaparral Mercruiser Prop Question

    I think if you want to do watersports with 8 people ( big ask of any boat) you will need to try a couple props, best to find a shop either local or on line that you can talk with and try a few. I have never used TP props but have read mixed reviews here. I had really good luck with Michigan...

    Boat bogs down after 30-90 minutes

    If you get above 170 with a 140 thermostat its too high. You may be sucking air or bypassing too much raw water if you have the check ball system Would not use until you figure this out.
