My son inherited my dads Javelin, mid 90s 389 and we are trying to get everything repaired back to functional. The trailer has the bow roller on the arm that drops down and the springs that are on it now are not strong enough to keep it up to where it needs to be. The bow roller drops all the way to the frame and we don't know how far it should go. Does anyone know what springs we need or is there some sort of mod to fix this? The boat is running good and he has fixed most of the issues it had and still making repairs/improvements but this bow roller is the biggest problem that needs to be fixed now. Thanks. FES
