So I've got a similar issue and need some advice. I've put 100 hours on my 2015 Scarab 195 in the past 6 months. At 7 hours I had a loose nut damage the impellar, and replaced under warranty, no biggie.
Just after 100 hours on the boat, we suck in a 3/8" rope and the engine suddenly shuts off. We couldn't pull the rope out. We were in Catalina, 20+ miles from the launch ramp in Long Beach. While waiting for the tow boat and while getting towed back, something is leaking and the boat takes in more water than the bilge pump can handle, and the engine compartment completely floods, whole boat nearly swamped. We had two 5 gallon buckets to keep the boat from sinking, or at least taking on more water. I'm still not sure if the boat would've sunk but service rep said it would've like a tank.
I got the boat home, cut the rope out, and won't start. I plugged up the boat and hose water into the boat, the water leaks right out of the drive shaft.
Right now, the boat is at the dealer, having a water evac done, diagnosis, and I've filed an insurance claim. I am not sure warranty could do me any good? I'm very dissapointed that a measely 3/8" rope could kill my engine and nearly sink the boat. I've taken the boat to Catalina and back 4 times, so now I need to be extremely cautious.
After this issue, I'll likely need a new engine at the least? Worth trying to save an engine full of salt water? I'm concerned if we don't put in a new engine, I'll be paying for repairs and then a new engine in the near future.
Also, currently I have the 200 hp, and get a top speed of 35-39 mph. If I get a new engine, was thinking maybe upgrading to the 250hp, but I've read that only increases top speed ~43mph, which isn't a drastic increase but could help.
Thank you in advance for any advice or thoughts.
