    Plywood cover for open bow

    you still have not answers why you need it. as I stated, with the sunbrella bow cover on you can literally plow into a 7 foot wave at 20mph and the wave will wash over the canvas, up the windshield and land on your head. This was done with my SeaRay 190 often at slower speeds the water will...

    Plywood cover for open bow

    not sure why you would add something that ugly to the bow of your searay. the standard bow seating cover suffices in keeping water out of the bow area if you take a wave over the bow in 7 foot rollers.... BTDT and have the tee shirt. it will however slide the water up and over the windshield...

    What am I looking at?

    my guess is that the elastomeric sealing strip between the keel and hull is damaged or your keel itself is leaking. pouring water into the keel V trough will run to the back of the boat. that is what its supposed to do. yes, the boat is riveted together with 2 sheets of aluminum and a formed...

    Query about raising outboard 6" on transom

    buy a jack plate. that way you can raise it for mooring and then lower it to use it. if you raised the motor 6", you would never get on plane, and even though the pickup ports are below the water, the water pump wouldnt be and it would never prime and you would toast your impeller the first...

    Blue smoke during warmup

    since your boat is a 1990, you either have a Mk IV motor (2-piece RMS, flat tappet cam) or a Gen V motor. if its a gen V i would recommend upgrading to Gen VI (1996 and later) the 1990 Gen V blocks are the first year of priority mains oiling and there were goofy issues with the steam holes and...

    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...

    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...
