I recently bought a 1998 glastrom with volvo penta 3.0gs and noticed it overheated so I took it to a shop and they diagnosed the Impeller needed to be replaced. After getting that done I took it and it works fine as long as I staty riding below 30mph or it will raice temp to 200 or over but will cool down idmediatly once I slow down again... I calle dsho and they claim it may be head job (or gasket) which i dont think since the oil looks good but I can be wrong. Any sugestions? Thanks, Will
