    Reliability of 1998 25hp EH

    a well maintained motor is reliable as he# a neglected motor run hard and put away wet (without any of the maintenance racer mentions) will die. most motors dont die, they are murdered from lack of preventative maintenance

    What´s the best replacement for AQ271C (or 570) 5.7 GM engine, ideally stroker?

    the edelbrock is a good manifold. same as the stock Volvo Penta vortec manifolds that I ran. go with a 1" minimum, 2" preferable carb spacer to increase plenum volume under the stock carb. will give you some tuning tips on the holley later a good timing set (melling, cloyes or comp cams), a...

    do you have any traces of rust on the top of the valve covers, if so, you could have them rusted thru around the return that makes the lip. check the condition of the breather elbow grommets. and breather tubes. as stated above, doubt the rubber gaskets under your valve covers are what is...

    Deep cycle battery box

    I would go with either AGM or Gel and not worry about the box. Battery boxes are for flooded lead acid batteries

    Blue smoke during warmup

    12k is a lot of money for two rebuilds. I would inspect everything prior to buying parts. Line hone and decking is a must. I also recommend zero balancing A new crank is about the same cost as reconditioning the stock crank, and new rods are cheaper than reconditioning. I would seriously...

    No spark plug spark... 170 MC , 1985 Sea Ray

    could be sloppy dizzy bushings pull the cap, pull the rotor. grab the shaft and wiggle. if the shaft moves more than .007" radially or .020 vertically, pull the distributor and go to napa and spend $10 on two distributor bushings. then put the thing back together, re-gap the points, verify...

    Oh this can't be good. MErcruiser 5.0L loud clicking.

    a brandy new 5.7 longblock GM motor from GM is only $3200. add a new set of manifolds, some gaskets and do the job yourself and your into it for $4500 local machine shop (not your marine guy) could probably rebuild your 5.0 GM motor for about $1500 heck, even if you had to buy new heads from...

    sea wolf construction

    you should have an access cover to inspect the fuel tank. that cover will also give you access to the vent and fill hoses. 28 years is a long time for rubber bits.

    1st time driving from NY to So Fla...route advice needed

    taking 3 days to drive from NY to FL would drive me nuts. Im the type to get in and simply go...... and 20-30 hours later I am at my destination. We routinely drive from Florida to Wisconsin (driving past @redneck joe ) and do it in one trip, with a 2 hour nap at a rest stop along the way...

    Blue smoke during warmup

    compression should be 150 psi. below 125psi you start to loose performance while mercruiser says you should rebuild at 100 psi, I like to rebuild at 125psi. at 80 psi, your motor is toast
