Compared to cars, towsport specific inboard marine engines produce more low end torque per displacement at lower rpms and have different cooling systems than that of an automobile.Everything that Indmar offers from propylene glycol anti-freeze, transmission fluid, synthetic oil, blended oils, filters, fuel treatment and other vital fluids is formulated to be the very best inboard marine engine products you can buy
Go to an auto parts store, and get a hydrometer to measure the temp the coolant will freeze at. Should be less than $5. It will tell you how low the freezing point is, and should be able to get an idea of the percentage of anti-freeze. Normally it is 50-50. Pure antifreeze will not dissipate heat as well, and you could overheat. Probably some other issues as well.
Welcome and see attached for capacities. If it was a complete system flush your only half capacity. If he only drained the radiator you should be OK. I use nearly 100% coolant/antifreeze and have never had an issue, but since GM started using Dex-cool, I stay with the recommendations in the OM. With the
In either case, it would appear to be low. I am guessing that it was flushed with water, and the radiator was re-filled with pre-mixed, giving the worst case scenario. I would go talk to the mechanic and figure out what he did, and have him drain some out and add pure antifreeze - the premix will not get you there now.
A common failure point on the Crown Victoria Police Interceptor was the intake manifold. Beginning in 1996, Ford used a plastic intake manifold manufactured by DuPont, which also had an integral plastic thermostat housing and anti-freeze crossover. As these vehicles were commonly used for emergency style driving and often endured long idling times, these intake manifolds quickly proved to be problematic. Cracks would develop along the thermostat housing area, causing anti-freeze leaks and overheating issues. Misfires have also been reported, as leaking anti-freeze may seep down into the spark plug wells.[19] This resulted in a class action lawsuit against Ford.[20] Beginning in 2003, a revised intake manifold with a bolt-on aluminum thermostat housing and anti-freeze crossover was produced and fitted to all new vehicles in an attempt to remedy the issue. While they were less failure prone, these intake manifolds proved to be problematic as well. Another common failure point on these intake manifolds was the rear heater hose fitting, located on the rear right side of the engine. It used a plastic nipple to connect the heater hose to the heater core. The plastic nipple would often split off from the intake manifold, causing rapid anti-freeze loss and overheating.[21]
