Yes, plenty of changes made to the overboard drain system made in those years…The drains were removed and that funky recirculation system was added. I don’t think we ever got it right, idle quality went down hill and plug fouling issues followed. Is this a new powerhead still in the box? If so, were there any instructions. I don’t know how this swap is going to work out with a mix of the overboard drain and recirculation systems…
