Do they want the carriage to go by boat? Yes. Boat routes relevant? Yes. Do they want it to go by road? No. Specific roads relevant? No.
So they was a safe road to Lahore but they decided to go by ship, right? Correct.
Were they afraid the horses would not make it? Assume yes. the carriage could get damaged on the way? Assume yes.
Did they tell the maharajah that they came by ship? Irr, assume yes. or was it rather along the lines "look how strong our English horses are, they drew the carriage 500 miles uphill and are not the least bit exhausted"? There was no direct deception involved.
Lahore is not located directly at the Indus? Relevant? No. Did they go the last part by road? Assume yes.
Did the trip by ship serve still another purpose? Yes. Did they want to test how far up British vessels could go? Yes. Did they want to survey/measure/test/create a map of the Indus? Yes!
Relevant that a ship could hold more people than a carriage? No. Did they secretly bring in soldiers? secret agents? into the Sikh territory? No.
Or, much simpler: they needed the ship to get back after they delivered the carriage? No.
SPOILER
The British knew that eventually they might have to deploy armies along the Indus (which they did in the 1840s, conquering Sind and the Punjab). For this reason, they needed to survey the Indus River, as it would be their primary support route during a war in that part of the country or in Afghanistan. The gift of a carriage and horses was a thinly-veiled excuse to travel up the river, as the gift could not reasonably be expected to march a thousand miles or more along roads without damage or injury. Some decades later, the Russians similarly surveyed the Oxus River north of Afghanistan whilst smoothly delivering a massive pipe organ to an ally.
