My question is, since gelcoat is a polyester resin, thus sticky when exposed to air, can I add wax/hotcoat to the gelcoat so that...

    because of its property to fill cracks I was wondering if Superglue would be a good filler for crazes and such. The hull of my boat has some long crazes and I want to make sure they are sealed. Has anyone done/used this before? <br /><br />Adam

    Hi Nautijohn,<br />first I would like to apologize for any implied attack on your advertising photos of the trim tabs. Though I still think the horizons should be horizontal (for aesthetics and proper representation). Secondly, I am interested in purchasing a pair for my 12' Avon inflatable...

    difference between Tohatsu 15 & 18?? Going to buy. Help please

    Hi, <br /><br />I'm going to buy a Tohatsu motor today. I am wondering if the rumors of a 15 being the same as an 18 except just with a restrictor plate. Is this true? Can someone please dispell this myth if it is? Or is it a bigger carb, fuel rails, etc? :confused: Thanks all<br /><br />Adam

He says it has less than 30 hrs on it. Ok here are my questions. Is $1500 a good price? And: can anyone tell by...

    1975 Mercury 20 hp throttle problems

    Hi <br />my 1975 Mercury 200 20 hp has a very rough idle. Even if I adjust the idle screw you can't really discern a performance difference. Also When I try to throttle it up the engine will begin to bog. The only way I can throttle it up is by closing the choke 80% then throttling up then once...
