    help with right hand left hand motors rotation.

    Got a call today from a freind of a freind about motor rotation on a 454 BW 72 series equipped boat. I thought I had this down but trying to diagnose the problem I got confused. I always thought the trans with the reduction gears such as the 1.88:1 turned the wheels the same direction as the...

    Oil pressure question

    My 1988 year 454 crusaders maintain 40 psi if I keep the RPM around 2300. When I cruise them at 3000 my starboard motor drops to 30 but the port is good. This started after the latest oil change. Maybe a bad bypass in the new oil filter? Any thoughts? The motors run fine and don't seem to be...

    Throttle body fuel injection.

    Just lightly thinking about running throttle body fuel injection. Most units I'm looking at need an O2 sensor in the exhaust. Was thinking about manufacturing a piece to fit between my log manifold and the elbow to mount the sensor. Any thoughts on this? I should say they are the 454/350 horse...

    '88 454/350 deck height

    Was curious if anyone knows the deck height on our older 454's. I'm shopping motor parts for my next haulout and get asked this when talking to parts people. I know there was a standard height and the truck motors seemed to use the taller deck blocks but not sure about the marine engines. Can...

    Exhaust manifolds

    There was some discussion on another boating forum about the advantages of switching from the older log style manifolds on the 7.4 motors to the center rise style with 4" elbows. Was wondering if anyone has done the switch and seen any honest gains in H.P. or mileage. I would think with the...

    Delco EST module

    MakoMark, Read thru some threads here about the EST dist. I believe my portside 454's module is dead as I get the lower RPM's when I energize the timing jumper but when I disconnect it timing jumps to 14 degrees and stays there all the way to 3500 RPM. I read about the modules you...

    Teflon flax packing

    I repacked my 1 3/8" shaft packing with the white Teflon impregnated packing and used the Syntax grease. I did this while in my slip. I have the tounament type gland with two 9/16" nuts that you tighten instead of the one big gland nut. I'm a little concerned as I don"t have a significant amount...

    Starter or neutral safety switch?

    1988 Blackfin 29 with 7.4 Crusader 350 H.P. Starboard motor wont turn over. Am I correct in assuming if its the neutral safety switch you wont hear the solenoid engage when trans is in neutral? I can hear the solenoid click when the trans is in neutral but the starter wont engage. Trying to sort...

    3" Elbows by H2O

    I found some 3" Elbows made by a company called H2O for the log style manifolds. They are manufactured in Taiwan. Anyone used these? Opinions? What say you experts? Are these the Chinese ones you folks don't recommend? I know Barr is the best....

    Crusader 3" elbows

    Hi folks! As stated in previous thread I want to change my exhaust elbows out while I'm on the hard. I found a great price on some "Crusader" elbows but am a little suspicious they might be made in China. Does anyone have any info on the current manufacturer of Crusader branded exhaust...

    Which carburetor?

    I was wondering if anyone has a favorite carburetor they like on the Crusader 454/350 H.P. Thermo Electron motors. I currently have the Rochester Quadrajets that I rebuilt with Cliffs kits and they run great but there are guys in my marina with heavy boats that say they get a couple tenths...

    plastic nuts for alignment

    When doing my alignment do I need to loosen the motor mount bolts or can I turn the plastic nuts with the bolts tight? Is there a special spanner to fit the holes in the plastic nuts or can I turn them with a stubby screwdriver?

    Delco Remy EST distributor timing

    I've read a lot on the net about adjusting the timing on my 454/350 engines equipped with the Delco Remy EST distributor but there is one thing I don't quite understand. If I'm checking total advance timing at say 3000 rpm I don't need the shunt installed but I can read it in the normal manner...

    Dexron lll

    Hi guys! I just did an engine and transmission oil change. I did a search on here and came up with the velvet drives needing 3 1/2 quarts of Dex lll. The only stuff I can find is a Dex lll/Mercon fluid. I put it in but in hindsight thought I should ask the experts if this is the right...

    Just curious

    Sitting here with it raining and a little bored I have been thinking about my next haulout. Hopefully I wont need to do any major engine work. I've noticed the cautions to the 5.7 guys about quench area and was wondering if this is a problem with the 454 BB motors? I see rebuild kits fairly...

    I just talked to a guy at the marina that bought the 496 c.i. 450 horsepower 515 ft lb. version from these guys http://www.1800runsnew.com/ Any body ever bought an engine from them? There is a shop here locally that I talked to stroking and boring the old 454 to 496 but they still use the small...

    Engine zincs and heat exchanger rubber grommets.

    I have the zincs for the oil coolers and heat exchangers thanks to this forum. Took the end caps off the H/X and they look good. I found a set of small white rubber "O-rings" in a drawer left by previous owner. When we took the end caps off one of the H/X had these around the bolts between the...
