    timing question

    I am ready to set timing on my rebuilt 454 tbi reverse rotation motor. What is the best way to do this being its a reverse rotation motor? I understand I have to put the ecm in base timing mode, just not sure of the correct way to read the tab.

    horrible mercruiser manifolds

    Can I use crusader manifolds instead of mercruiser to avoid leaking into cylinders and wrecking my motors?

    wont go over 2000 rpm

    I have a 454tbi mefi 1 motor that when I reach 2000 rpm it backfires out of the throttle body and bogs down to 1000 rpm. After I pull back the throttle I can run the engine at 1900 rpm all day with no problem, just not beyond that. I have changed the ecm, coil, checked base timing, plugs and...

    cuts out at 2000 rpm

    I have a 454 tbi with a mefi 1 system. When I accelerate to 2000 rpm the motor cuts out and drops to 1000 rpm and pops through the throttle body. Once it drops to 1000 rpm I can then accelerate again but cannot pass the 2000 rpm threshold. The motor runs great at 1900 rpm just not any higher. I...

    new to marine power

    Hey guys I hope to be picking up my new boat Saturday and have a few questions? It's a 32' luhrs with 454 marine power tbi. Are they similar to crusader and how much antifreeze should I expect to use for winterization? My other boat sports 270 hp crusaders and was wondering if they are similar.

    270 hp missing?

    i took the boat out today and both engines purred on the way out of the marina until i throttled them up when the port engine started to sputter and pop out of the carb and the starboard motor ran really rough. i was able to make it back to the slip and both engines were running really rough...

    Burning up coils?

    I have 270 crusaders and one day the one didn't start so I put a new pertronix igniter and a stock coil in it. Took it out for a run the other day and once I got the rpm's up she sputtered and died and would not start. The salesman at the marina told me I need a high power flame thrower coil to...
