What to Do ??
:dance: I think there's no one answer. I've trailered my H260 over 3000 miles in the past year, with my 9.9 hp attached, and have not seen any stress marks etc. I have an SUV sooo I'm not planning and taking the engine off to put inside my carpeted and usually full rear cabin. Plus I'm not crazy about the strong smell of oil on long trips. :Liar:
I figure since I keep my trailer with leaf springs in good shape and don't drive like a mad man, and assume (rightly or wrongly) that my transom and bracket was originally made to transport the PROPER SIZED engine, that I should arrive at my destination with an engine attached. I still do a complete safety walk around prior to starting a trip. (old pilot days).
BUT then again after all that I could loose a wheel, skid into a deep ditch and loose my boat, motor and trailer, and curse myself for not having the motor in my cab! :cussing:
