when it cold it will fire on all 4 then after it runs awhile it starts losing fire on 2-3 cyl. and then won't start only fires on one i think it's the power pack
just replaced my power pack on my 1977 85hp. I lost all 4 cyl after about 15min. Would have to wait about 20 min. and it would start again. <br />www.seilermarine.com as good prices on power packs. mine was $90.00 included shipping with 2 year warranty. good luck
